Nice video. Thanks!!
good vid, nice and straightforward
It is related. You have to have tight joints (rod ends and ball joints) then proper alignment. The slop in your tie rod end is allowing a wheel to toe out or in which steers the car. You compensate by turning the wheel. I did tie rods and alignment on my old Ford F150. Wish I had filmed that. It is not that hard. Keep Googling. Somebody had to do a good video of it.
Thanks for making this video. I’m going to replace my pinion seal when I convert my WJ’s rzeppa front driveshaft to a double-cardan/u-joint setup and this takes a lot of the uncertainty out of the process.
thanks, also a great vid for the wobble. Definitely have some worn out bushings where the tire rod connects to wheel mount… also should mention my jeep pulls to the right on a straight road and have turn my steering wheel to the left to compensate. would this be a steering shaft problem, or alignment or part of the tire rod issue?
Wobble and camber? I’d check the tie rods and drag link. Watch my steering wobble vid. Mine was just stabilizer bushings, but you will see the technique for finding it. lay on the ground and have someone work the steering back and forth and look for movement in the rod ends.
Great vid, definitely have to take care of the diff… ive been trying to read up on a problem Im having with some serious wheel wobble, also got some serious camber wear on my front tires. any diagnosis? where should I look to find/fix any potential problems? (newbie mechanic) 🙂
Great video thanks for taking the time to make and post it
This video is gonna save me a bunch of money thanks
Good video man
Cheers mate great vid
Excellent and thorough!! Nice vid thanks
So this should be similar to doing the seal In a 96 Cherokee with five speed rite ? Great vid enjoyed it thanks
Doubt it. I am thinking axle bearing.
My jeep has been making a grinding noise from the rear end but it only makes the noise when i am slowly turning, ( in first or 2nd gear) and only after the vehicle has been driven for more than just a few minutes. I have taken apart the rear diff and everything seems to be in order, could my problem be the pinion and seal?
thanks man
Not necessarily. It could be a cut seal. Try replacing it once. If the leak comes back, then you will have to inspect further.
Nope. Drill three holes in a piece of angle iron. bolt the iron to the pinion through the outside holes. use a bolt and nut in the middle hole to jack the pinion out of the case. Or just hit it with a hammer and see what happens. 🙂
Do you need a gear puller?
when you have a pinion seal leak, do you need to replace bearing or the gear too?
hi! great work! I have a problem with my KJ and guessing that it is the transfer case but would you please look at my videos and let me know what the problem is?

Thanks again. Your videos are informative and well done. Give us all the jeep maintenance project videos you can muster up. “Jeep On!”
Yes. The part # for the seals might be different, but the process is the same. Do your front one first so you get good at it, then film changing the rear and share.
hey, I have a Jeep 2002 Wrangler. both the pinion seal the front and rear leaking. Is the process the same for the rear that is the front pinion seal replacement?
Should be cake the 2nd time. Inspect the pinion shaft for nicks. Maybe it took a hit from a rock or something and is cutting the seal.
I got under the Jeep and noticed that the seal is only leaking between the yoke and the seal, best guess is that it is either damaged or has a larger ID than the yokes OD. Good thing is that the seals are <10 bucks.
I did lube, wiped a little diff oil on it, put rtv on the od. I wonder if the nut iOS loose or it is leaking between the pinion and the yoke ? I’ll get under and take. Better look. Thanks for the good post.
Ouch. Did you lube the inside of the seal before putting it on? You can tear them. If you figure it out, let us know.
Fantastic video, I followed and did mine, it is now leaking I fear that I tightened the nut 1 turn too little :(. not sure why it would leak after being replaced.
Thank you thank you thank you
Yes, same process except you might not replace the seal or change the fluid. Actually, once you get the yoke out, I’d be tempted to put it in a vice and try to drill out that broken bolt from the back side.
awesome video thanks. does all this info apply to the yoke coming off the rear axle? i have a 98 tj and i was replacing the u joints and broke a nut off on one of the caps. so now i need to replace the yoke…
Yeah, like most things if you take the mystery out of it, lots of people could do it.
Thank you very much for this video! Made this job seem much easier! Thank You
Mine didn’t. I am guessing that whatever is making the noise (my guess is bearing) is what causes your pinion shaft to run out of true and leak. Inspection time. Film and share, please.
Does the pinion seal make a rotational noise when its going bad?my 99cherokee has a slight drip leak and im hearing a rotational noise.any sugestions.thanks
Very good thanks!!!!
Chevy Astro, wooo! Hopefully it’s a 1st generation w/ AWD a lift kit and some Super Swampers. That would make a good video. 😉
Great video, same procedure for a chevy astro van, I guess they are pretty much all the same. I’m buying a torque wrench tomorrow! Thanks for the help. It makes a big difference to us working guys who can’t afford to pay someone else to do what we can do ourselves thanks to people like you.
Yeah, if a picture is worth a thousand words, what is a video worth? About $4 a month according to Google. 🙂
Write-ups are great, but this is far easier to understand than most write-ups are. Thank you so much!
Yeah, mine was on the ground in park. I can’t think of any reason to remove the wheels or axles. I like the parking brake idea just in case.
