WTF Trucks How to replace the rear transmission seal on 1997 Chevy 1500

This is not easy....You will need air tools ,spray penetrate,seal remover,hammer,and Jack stands..Seal installation tool,.All proper tools..safety glasses.correct seal replacement.,new lock nut...Set park brake,block rear wheels,raise vehicle front and safely place jack stands under each side of lower control arms..Spray lube front drive shaft mounting hardware and lock nut that holds Yoke on front diff..Let it set to penetrate..put vehicle in neutral..Mark shaft to yoke location and direction perfectly because it has to be installed in perfect timing exactly how it was removed..,Remove drive shaft..Remove lock nut and yoke from front diff...You will have to hold yoke while removing lock nut because it will spin..PROTECT HANDS..( These can be VERY DIFFICULT to remove..Sometimes they have to be heated..You will need a yoke removal tool if it doesn't tap off with hammer...Mark exactly the yoke to spline location before removal..You can take close up photos however Mark it also to be sure...If you re-install it wrong it will vibrate terribly..Once yoke is removed You can remove seal.Make sure the new seal is correct...CAREFULLY..DO NOT DAMAGE SPLINES WHILE REMOVING..Sometimes even the perfect seal remover will damage splines..So cover it to protect spline threads..Clean all areas once seal is removed..Make sure nothing is pitted or damaged...Install new seal with installation tool..Lightly,perfectly tap it flush with diff..You can use old seal to install new seal if you don't have installation tool But only a pro should do that...Once in place Line drive shaft yoke with your marks and tap it on ..Use NEW LOCKNUT AND TORQUE IT TO SPEC..Install drive shaft as marked..torque to spec..Lower truck and check fluid..Complete..

Remove the driveshaft. You need an impact gun to remove the pinion yoke nut. Pull the yoke out and replace the seal. Make sure you tighten the pinion nut to the correct torque spec. (The dealer can tell you how tight it needs to be.)

There is a special tool for removing the bushing.The Kent Moore number is J45380.If your not sure if the bushing is bad then just replace the seal and sometimes the yoke is worn where the seal rides on it.You will see a mark where the seal rides.If you can feel it with your nail the rule of thumb is that it is about .005.This could cause a leak.Sometimes they make a sleeve that fits on the yoke and will take care of the wear area and the replacing the seal should be good enough.Hope this helps.Good luck.

there is a long bush type bearing in this tunnel just at the end were the seal fits in it can were out and let the prop shaft flap about, this in turn rips the seal to bits,,,also the yoke has a polished part on the end that go's over the spline into the end of the gear box tunnel the seal can were a groov into this part, and no amount of new seals will stop it leaking them as the new seal runs in this worn out groov, again ripping it to bits,,,test the long bush type bearing by holding the prop shaft yoke and pushing it up and to the side, if it moves about replace the bush in the end of the tunnel as well,, its a push in fit! with a big hammer!!
if the yoke has a groov in it you need a new prop as all prop shafts are balanced so you can just fit a new yoke it could throw the car up in the air when your driving it down the free way,,,,by shaking it apart
i hope this is of help to you

well if the axle is leaking you dont need to adjust the shims, it needs a new seal. pull the brakes off open the rear diff there will be a c lip holding the axle in, remove the c lip pull the axle repalce the seal on the end of the axle tube, put it all back together and you done

i had the same problem and it turned out to be the gasket on the rear main seal housing not the rear main seal.

Hello,you need to remove driveshaft to be able to get to the nut.Remove the nut (MAY BE VERY TIGHT) and pull the yoke or flange as you called it out & you can pop old seal out & new seal in.You may want to smear a tiny bit of grease or vasoline on outside of seal for easier installation & also on the rubber part of seal so itwon't get damaged when you re-install the yoke.Hope this helps.
