- In this video I will show you how to replace upper and lower control arms in your Jeeps front axle. This process is very similar to other vehicle models but today I will show you how to do it on a Jeep Cherokee XJ with a Dana 30 Axle. This process may be similar on other Jeep models such as the Grand Cherokee, Wrangler, and Comanche. I will show you how to do the whole job from start to finish. If you have any other questions that the video doesn't cover make sure to comment below and I would be happy to answer.

If you’re doing both upper and lower, do 1 at a time or the axle will shift significantly
sharing your skills with us you are.... mhhhhrrrrmmm :)
I did one at a time and the axle still shifted a lot.... I couldn't imagine taking both off at the same time !!!
doesn't matter as much when all of the bushings are absolutely destroyed!
I'm a machanic and a construkcion worker and a machanic engener and I love your awesom Chaneel. Greetings from Slovenia 😎😎😎😎
Your videos are always amazing. They make me feel like I can fix my own jeep! Thanks man!
Thanks for the support, I'm here to help anytime!
Great Video Changing the ones on my 2004 TJ Thanks Austin
Nice job Austin.
Thank you Austin, another great video
Great video and easy to follow. Thanks for sharing your How-To. I may have to use this very video on my own XJ ! 😄 🐞IIII🐞
Very good video, well explained
Your working on the exact same jeep i have had for 12 years now, i have done so much work on it and spent a lot of money but worth every penny, it's a 9821 jeep lol
Thanks for the vid. I’m doing this on my 98 very soon. Also if that don’t fix the death wobble it’s probably the track bar
It has fixed it, track bar and tierod ends have all been replaced
my passenger side track bar bolt keeps loosening til the wobble starts, headed out this morning for a new nut and bolt
Excellent 'How To' video! Great explanation of how to do and why to do. Helped my gf learn what I was doing to her jeep and remind me what I'm doing.
Glad it helped!
Great job young man I gotta do a 93 zj
Did this on my Grand last weekend, If you remove the caliper & rotor you're impact should fit on drivers side ? I use swivel heads also sometimes because the IMPACT IS GREAT & YOUI HAVE THE BEST IN MY OPINION OJ.
Thanks, Austin, new subscriber here... I love your no-nonsense approach style and so far your music has been pretty good too!!
Awesome! Thank you!
nicely done, very descriptive. haha hangin off the rotor to get them click clicks for torque
Just getting the shot for all the ladys
May want to tighten those lugs in the recommended 5 point star pattern
Its amazing from all the postive detailed information that this man is giving you have to focus on the one part that he over looked because he probally figured most people know how to tighten lug nuts.
@HexagramManNot that it really matters since this was a video about control arm bushing replacement procedures.., but a good 2 cents might help someone out there. I always just go around with a partial tightening first, until back to the lug I start with, making sure the hub is on all the way, then I tighten them all good and tight with my breaker bar.. No problems what so ever for the last 10 years, and I use my spare a lot living out in the desert. So really it comes to mechanical know how, first and foremost, and of course the threads need to be checked each time wheel lugs are removed (Are both the stud and lug threads clean and still fully intact?)..
Every bump I hit I hear all kids of rattle banging like something is loose. Everything else is new except this. Going to give it a try. Also have had the feeling that the axle floats a bit on the road when driving faster.
Have the LCAs, bushings, and bolts for this project, too. Are the bolts on these the same as the rear leaf springs (not the same as the UCAs)? Thanks.
The rear leaf springs have the same size bolts but are a little longer.
Did you have death wobble and did it help fix it
Cool, Who is the music in the beginning of vid ??
What brand are these control arms and did it fix or improve the death wobble?
It fixed my wobble by 70%. I believe these were made by SKP
@@OutJeeping I fixed my death wobble by 100 percent it was an oblonged hole where the center arm hooks to the passenger side upper chassis from the front end unit, the factory mounting hole is bigger then the fastener bolt, factory flaw, so you need to re drill center bushing of the center arm to I belive 7/16 and install new hardened bolt, never wobbled since
What size socket?
It seems a 13/16 fits really well, but I don’t want to mess up?
2000 XJ
The lowers are 21mm
thanks . looked easy but now I'll use the strap and save some skin
I have a quick question about lower control arms. I got a pair of lower and upper control arms and I noticed that the new ones (not stock) are about 3" longer.(lower ones) and not sure about the top ones. If I replace those with the longer ones (which are far beefier) will it raise the front end alot?
The XJ 1999 Jeep Cherokee is currently stock with the exception of rear leaf spring links. I put some longer links in place, which is currently set to the least aggressive setting.
Control arms will not change lift, they only affect where the axle will be located. With longer links they are meant to go with lift springs to return the axle to the center of the wheel well and give appropriate pinion axle.
I have some really serious vibration after replacing old leaf springs with stock new ones. I believe the angle must be off. The ride height is now 2” - 3” higher. The vibration is less when the Jeep has 4 people in it- almost normal- but when I drive it solo the vibration is scary. So I am going to put stock shackles in- and will measure the angles. It appears as if the pinion is pointing down too far. - I will have some shims tomorrow. I removed the front drive shaft and the vibration is just the same or worse.
Do you have a video on changing the uppers?
Not currently
@@OutJeeping Although your explanation on how to replace the uppers made sense.
id like to know where you secured your ratchet straps
Anywhere solid really, I went around my sway bar. It doesn't have a lot of force but it's nice to have it as an extra hand.
Did the bolts on this Jeep or any other XJ you've done this on, have any troubles with the bolts? Like so rusted they snapped?
With the lower control arm bolts, I have always had great luck with getting those out nicely. On the other hand, leaf spring bolts are another story.
@@OutJeeping Good to know. My project day next weekend includes the LCA's. My little impact with a short socket fits just barely on the bolt on the front side on the driver's LCA. Looking forward to a "easier" project since im doing shocks as well that day and the bolts for those..
Do you know what are the specs for torquing the bolts on the arm controls ?
I mention that towards the end of the video
85ftlb
What size are those copper tires? They look good
Those were 235x75x15r
I like the rust. that's mine NE
did this fix your wobbling problem?
It has for me
Where can I buy a bolt 21mm? I lost one of them??? Please help!!!!
Fastenal or other automotive distributors may have it. It is not a common size so it will need to get special ordered.
did this get rid of the death wobble you had?
It did by 75%, the upper control arms fixed the rest.
Ok. Passenger-side lower control arm nearest the firewall been working on it all afternoon it will not come out I cannot break it loose -two sets of prybar’s cheater bar PB blaster and now I’m using a jack and a block of wood to push against a long armed prybar the prybar is now pending a couple of degrees having zero luck! Help!?
Try heating up the nut on the back side then go at it
OutJeeping will try tonight! Thanks!
Hi! I hope you can help me😏I have a problems with my 1998 Jeep sport Cherokee the electrical fan stays running wend I turn off the engine can you help me? I hear is the relay switch can you tell me where is located?? Thanks in advance! And keep helping with your very great videos you’re a great mechanic!😊 👋from 🍊California 10/26/19
On my '03 it's mounted on the right wheel well behind/under the headlight.
B thanks for your kind answer but we look already and we didn’t see any cables that could come from that part of the jeep🤔 thanks we’ll keep looking
There should be a fan relay in the fuse box underneath the hood I would pull that and maybe swap it with another relay and see if it works properly, if it does then you just need to replace the relay.
OutJeeping- thank you for your help we’ll look in to that......we found it! it is a black plastic box with a bunch of black square relays, thanks again and let’s keep jeeping.😀from 🍊County Ca.
Hammering bolts into their holes is how you ruin threads.
OutJeeping, did this solve your death wobble issues?
It did by 90%, it was fixed fully when the upper control arms were done as well.
How was your upper bushing that doesnt come attached? Looks tough to remove...
And the upper control arms replacement video is where?
I dont show in this video but I explain the process on removing them in the video if you watched the whole thing.
@@OutJeeping- I did watch the whole thing but maybe I was confused by this: "I will show you how to do the whole job from start to finish."
@@harrygatto Its literally the same process on the uppers and at the time I didn't need to do the uppers when I filmed this. I'm sorry that you didn't get to see the uppers removed but I did my best on explaining the rest of the job if you wanted to do them.
@@OutJeeping Thanks for your efforts, I've got the picture.
Stock height cherokee with death wobble?
Yep, it can happen when things are stock to heavily modified.
Bushings, tie rod ends, stabilizer shock, everything wears out eventually. And loose parts aren't good, regardless oc lift or no lift.
You’ve a lifted jeep in you’re just changing out the control arms now to get your caster proper !?
The Jeep I have in this video is a stock Jeep with no lift. I was replacing a factory control arm with another, so it shouldn't change Caster angle at all.
Did that fix your issue with the wobble 🤔
Fixed it about 70% but the uppers were shot too so those have to get done as well
@@OutJeeping ight going to try that mines runing cool but moves to mutch on bumps and pot holes
Why did you pick these control arms over any others
My plan was just to keep this Jeep stock for daily driving, so I basically got the cheapest ones on rockauto.com
Removing the upper control arm rear bolts are impossible. On the passenger side there isn't room for a socket and breaker bar. On the driver's side there is more room, but fuel or brake lines get in the way. Looks like the only option is to sawzall the bolts off and buy new bolts. New bolts are expensive from the dealer.
I was able to heat the nut on the passenger side and get it off with the ratchet wrench. I wasn't necessarily able to do the driver side that way because of the gas line.

Amazon says "this does not fit your 2000 Jeep Cherokee XJ". WTF? AND, when asked if this solved your "death wobble" (the point of the entire process), you have stated at least three different answers in your replies (70% better, 75% better, 90% better). This seems very unscientific, especially without showing us a test drive before and after. I personally don't trust a teenager giving automotive advice, not 70%, 75% or 90%. Thanks, but I'll find other videos with authentic proof that their labor actually works 100%.
Ha! Do what you gotta do guy. It did reduce the occurrence of death wobble on my Jeep but every Jeep is different on how parts wear. The upper control arm bushings ended up being the final culprit to contributing to death wobble. No it wasn't a scientific test for the reduction in death wobble. The purpose of the video was to show how to replace the lower control arms not how to cure your death wobble. Once again every death wobble case is different with how components wear on every Jeep. Apparently you don't trust yourself either which is why you are here in the first place.
