This is the one thing I do not like about my C4s (I've got two of them). Jacking without damaging is not easy. I made an adapter block that makes jacking much easier. If you like, I will make a video and send it to you.
Yes, that was a correct bolt on the diff - I just removed the D44 (you have a D36 since yours is an automatic) from mine yesterday. Dropping it to reseal it will be a fair job - you pretty much have to drop the whole rear suspension and "while you're in there......" will become quite a project. When you get there remember that C4 rear suspension operates in a bind. If you replace the rubber bushings with poly bushings, they will oval out at the bolt holes from the bending action. The only right way to fix it is to replace it all with heim joints.
I love that you’re doing C4 videos now too Chris. While I love my C5, the C4 was my first love, and I will likely be getting one again once I find the right one one. Keep up the good work my friend.
I really like this car. Now that the weather is nice how about a drive video of with the C5? How about Tortilla flats? That is a great drive and people may have not seen this place before.
Your video has brought back a lot of memories. I still have the 86 Z51, but we converted it to track use in 2017. I forgot what the car looked like underneath in stock form. I am starting to realize how much I must have spent to get to where it is at, lol.
I'm going to get those lift jacks. Your car has bottomed out a few times. Someone had fun! I have a full race motor with 1.75 inch full length headers. I still have room to work with them in.
I have a 96 Corvette convertible that I made and three-quarter thick by inch and a half wide by 12 inches long with an 1/8 inch deep groove offset to one side. I placed that aluminum block in the center of the vehicle on the pinch weld between the two jacking points making sure to miss any plumbing underneath. Then I can jack up the whole one side of the car with my floor jack and put jackstands underneath it then go to the opposite side and do the same thing it has been working for me for 15 years and I have had no problems. With the convertible I make sure to have the top lock down and the doors closed with the windows up to prevent any twisting of the body.
I've owned three C4s, and small floor jacks on each side will do the trick. Once the car is elevated a bit, a large floor jack can safely be placed underneath the front crossmember.
Always open all doors and hatches on c4s before lifting. Body twist is more than in the c5 and you can crack fiberglass if you dont. Great safety video! Keep up the great content.
Thanks for the information. I have been lifting my C3 with the quick jacks and noticed the gap in the doors increasing. I didn't think it was a problem. I will use your advice.
I use a floor jack on my C4, if I jack the front I put it under the large piece that the A arms are attached too. I have a piece that I made that I set on the floor jack and it goes in-between the exhaust and jacks up the rear of the differential. Works really good.
This was interesting Chris. The C3's came with scissor jacks which were located in the storage tub behind the passenger seat. I don't know about the C4's. But the C3's had a lot of exposed frame to use a floor jack.
Wow!! I haven't seen any c4 with these razor blade wheels man. They look awesome. I was in the market for replacement wheels, ended up with the 5 spoke c5 wheel, but only heard of these on an online wheel guide. Thats awesome man
It looks like someone has messed up your rear metal floorpans. Those are really banged up. I have to jack my up via the factory jacking locations because I need to use the inside pinch welds for my jack stands.
Clips are for a Bra I believe as I did install one 29 years ago. Getting ready to raise mine on the Quickjacks and great timing. An oil leak arose Sunday and I hope from something assessable... Having a ragtop I have pesky crossmembers and watch that diff leak, mine went all of a sudden.... Currently enjoying a 1987 and 2017.
Great video and information clearly showing what you are looking at. Keep it up. Always looking for information to help with my 85 Z51 purchased new back in the day. 😂 Thanks.
You sure brought back memories of my '95 C4 I had for 9 months that needed lots. The guy that had owned it for 10 years before me didn't even know it had a spare tire. And no idea what the word maintenance met. ha ha ha. But, once I sat in a C5, the C4 had to go.
I'd never switch to a C5. I love every rattle, shake and bump you can fell in the C4! But good for you that you got a Vette you really enjoy. They're amazing cars 😀
Chris you have a z-51 or a z52 optioned corvette` That being said they came with oil cooler, bigger radiator, extra pusher fan and bilstein shocks. The z51 had stiffer springs and the z-52 had stock springs for a little softer ride. Check your center console lid underneath and it will provide the code you have. This was an option and was not standard for these c-4's. these (especially the z-52 option) were not a widely bought option and are more rare than just a base c-4. I recently bought a 1987 and it has the z-52 option. My 1988 is just a base. And the 1987 I bought is the first one I have ever seen that came with fabric seats versus leather. It is factory as it is coded for this. Great information Chris. Keep it going!
Brother..GREAT VIDEO! Very few out there as detailed and informative. @mycorvettelife QUESTION: WHAT IS THE BOXY LOOKING THING ALONG THE OEM JACK POINT ON THE FRONT PASSENGER SIDE?? Sounds hollow to a knock..its just between exhaust and plastic rail alongside door that says 'jack location` thanks in advance for any help or insight
Nice detailed information on lifting points , not like the guy with the yellow C4 who claims he knows more than the pros do on lifting one . It's obvious you value safety . Nice job . Can you give some details on the quickjack please . Would love to have one .
Your QuickJack's are on the wrong side of the car. The way you have them would be for a rear engine car. I enjoy your video's, they have been informative to me with working on my C4.
You said not to use the factory jacking point that’s indicated on the side rail, with a floor jack! Is it ok to floor jack if it has a puck on the lifting point?
Cut a piece 2x4 the length of the front cross member to use on your floor jack from the front . I bought a new C4 6sp Zo7 in 94, took it to UK drove all over Europe, sold it 2003 and got most of my money back, looking for a 96 a the moment.
Very good and informative video. Has anyone ever put on a set of side pipes on a c4 Corvette? I'm looking for information about where the best places to connect them before I even take it to a garage to have it done. Thank you in advance
Most (but not all) Corvette owners read their owners manual, that's where I learned about my C5's requirement of pedestals to safely lift up the vehicle

I had a 93 convertible and the jack was behind the drivers seat, mounted on the floor. My 94 coupe has it in the compartment behind the passenger seat. And I've heard that some are on top of the spare tire. Bottom line GM in their capacity to not make up their mind on anything with the C4 it changes year to year. That said. I like your jack. Is it electronic or air? And where can I purchase one?
Chris, how's the fuel lines above the tank and vent hose looking? Mine was good for a bit, as summer came the tank pressure blew out the rubber behind the plate, above the tank. Behind the passenger wheel, the line exposes with a 90 bend check this area for rust, it will fail at this location as well and leak fuel.
I appreciated how clear this was. It got me thinking though - I like the Quickjack! Is yours a 5000SL model and would you recommend it to leave the car on for some time like winter storage?
I have a 93 Corvette and I would love to get a set of these Quick Jack’s. What model did you get? And was there any extra attachments you had to purchase for it to work on a Corvette?
I waited too long and they changed the lineup....so, based upon your experience, would you know which of the new improved versions of quickjack is the equivalent of the BL-5000SLX? Thanks in advance
Shit......... replace the oil pan.... its all pushed in in the middle. I would be worried about the oil pickup having an issue.... thanks for the video though....
@@christianmotley262 FYI... I have found that jacks with the small plate work best. I have a harbor freight with a 2.5 inch plate and it really works well, but my jack with a 5" plate is tougher to use because of those cross member supports.

Yeah, you can replace that transmission fluid at a later date.

Hi, I would like to see the video! Thanks
Some of the best auto camera work I’ve seen on TH-cam!
Thanks
I just got my 91 C4 yesterday. I work on Toyotas for a living, so I have no idea had to rack a Corvette lol. Thank you for this.
I use a floor jack each time I need to lift my c-4 vette; and yes I'm very aware of the brake/fuel lines. Use your head and you will have no problems.

As a C5 owner and after watching this video, I have even more respect for the C5 design team.
look at you! what no others could do you did 😂👍 I came here for a refresher and I thank you
I love that you’re doing C4 videos now too Chris. While I love my C5, the C4 was my first love, and I will likely be getting one again once I find the right one one. Keep up the good work my friend.
The factory jack is located in the spare time compartment
Good anatomy lesson. I have not been under my '87 yet, need jack stands or quick jacks. Thanks for showing me where to place them.
Just bought my first C4 and getting ready to jack it up. You’re video will be very helpful. Thank you
Fantastic, congrats!
Some C3 tech again following in the C4: rear spare and rear seat compartments.

Thank goodness for the thumbnail Chris. Here in Chicago there is a real problem with car jacking😄
Great undercar footage and best C4 jacking instruct on YT. Thanx for the content, as I am currently sailing that ship. Cheers !
I'm going to get one of them so I can get under my 89 Fe7 Z51. I'm watching all of your videos. thanks for putting them up.

@@kevingrantonic8812 Also, unlatch (no need to remove) the t-tops.
This is true if lifting one corner. if lifting the entire car evenly via a 4 post lift or QuickJacks there should be no flex.
I use a floor jack on my C4, if I jack the front I put it under the large piece that the A arms are attached too. I have a piece that I made that I set on the floor jack and it goes in-between the exhaust and jacks up the rear of the differential. Works really good.
I was hoping this was a 1" lift kit installation video 😅

Excellent as always! I just received my quickjack and hockey pucks. I'll be putting the '90 in the air next week .
Nice!
Any reason to use hockey pucks and not just some blocks of spare 2X4?
It looks like someone has messed up your rear metal floorpans. Those are really banged up. I have to jack my up via the factory jacking locations because I need to use the inside pinch welds for my jack stands.
Thanks for doing that. I almost bought the quick lift in Carlisle in 2019. The guy didn’t know if it would work on a C4.

Thanks for pointing out the best floor jacking positions. I'll be using those the next time I lift.
Cheers from New Zealand Chris
Every post i see in my facebook group of a c4 being jacked up they used those car ramps and some 2x4s to help get the car on them.
Many thanks for these informations, i own a convertible C4 with X crossmember underneath. Best regards from France 🇨🇵
Thanks for sharing.
Its common for oil to end up on the front cross member, I had a timing cover leak in my 95 and that's where the oil drips down too.

Deployment?
@@Dempdawg11 ?
Are those just regular hockey pucks or are they some kind of specialty spacer pucks?
What is that panel in between the transmission panel and the oil pane of the engine?
AC Delco has even larger oil filter than that,longer same dia.
Chris check your quickjack you motor sound like it is low on fluid or you didn’t open the breather valve.
Very good and informative video.
Has anyone ever put on a set of side pipes on a c4 Corvette? I'm looking for information about where the best places to connect them before I even take it to a garage to have it done. Thank you in advance

Did you find any info? Thx
Good Job Chris, where can I buy the two electric jack? thank you
Holy crap, the americans were able to do simple things
even more complicated than the frenchmen!
incredible

Very useful. I have a zr1. If I get the front of the car on low ramps, surely I can centrally jack the front on that front cross member? Thanks
What is the brand of puck on top of the pad? Thanks
Where did you get the electric jacks
What model of Quick Jacks are you using?

at 8:06 what if you customized a galvanized wire screen and spray treated it before installing?

love it
Lookin like you need a bigger garage to strip that one all the way down an rebuild it. Lol.
What I'm finding by way of a problem is the jacking point being so close to the jackstand point. This seems like an entirely unnecessary complication.
