Investing in crypto is the only big chance of making money
Crypto is the new gold
I wanted to trade Crypto but got confused by the fluctuations in price
That won't bother you if you trade with a professional like James alex
I heard that his strategies are really good
@@paultierney6677 Yeah My first investment with Mr james earned me profit of over $25,530 US dollars ever since then he has been delivering
great job great video.
great job thanks for sharing
Nice job 👍👍👍👍👍
That was different - thanks for the Mack video.
The jack under the drag link to get the taper unseated was cool, too. That nut you use to pound out the tapered tie rods - almost time for a new one?
Thanks for the video.
what's the size of the socket for front axle nut?
Tighten sequence- 250ftlbs, free throw, 600ftlbs, free throw 600 3 times while constant throw left and right.....or 400 ugga dugga then hammer....same thing
Hello from San Antonio, TEXAS. Does the King pin just wear down or what that eventually it requires a replacement? I love the tool that you use at 10:17. I have seen other videos such as a Pakistani helper/assistant who has just too much faith with his coworker using a sledgehammer while he holds a large drift with his bare hand! Just watch "Pakistani Trucks" or "Amazing Things Official" to get an idea as an example. GREAT WORK Semi Workin!
he miss his chance tu put grease instead of oil, grese is better, no more busted oil seal
Where can you buy that special socket for the cap on the bottom?
The socket you used to loosen the pin that is like + were can I find it ?
No draw keys... Hmmm
No thrust bearing nor shims either. Don't know if I like this design but mechanics
probably don't have a lot of influence on design.
@@jerrytalley337 I don't think we have any influence at all lol

Looked like there was a thrust bearing in that bottom cap. The lack of a pinch bolt was kind of weird. Wonder what stops it from turning in the axle.
@@dennissmith460 Yes, I didn't see the thrust bearing coming apart and must have fast forwarded
past putting it in. The bearing must be seated on the bottom of the king pin and adjusted up so
the full weight of that corner of the vehicle is on the axle taper and king pin and thus the weight transferred to the thrust bearing. The mechanic had to pound pretty hard to get the k p to unseat from the axle coming apart. Looking closer and rethinking this, this may not be a bad design. Just never seen it before. Taper is only on the bottom bushing and the axle bore. The thrust bearing must be able to be adjusted as bottom bushing wear happens?????? Top of pin is straight and uses needle brng instead of bushing. Guess it pays to watch closely and get the whole picture before commenting. Thanks for pointing this out Dennis.
23:51 the thread is left???
What year range (in general) did Mack use this design?
Mine is a 1990 ch613 and uses this style.
Don't think I have ever seen a tapered king pin before. Are they common or just a Mack thing?
This is an old style Mack King pin Mack Volvo use a different style tapered that has a nut on top
Yeah, usually you will find a large Lock nut on top and sometimes on bottom in Volvo cases
probably $600 dollar job
Don’t play games I need to know how to drive out that needle beating only reason why I clicked
Bushing driver, or something that fits in the king pin bore and still catches the bearing. You have to be careful going back in with the new beating as you can damage the race and jam up a roller
Well done sir please am a Mack truck mechanic please can I work with you please send me your number
