    Anyone tell me what’s involved ( once driveshaft is removed) in changing output shaft bearing? Does trans need to be removed? It’s had a very small amount of movement for a while. Will be doing clutch anyway. Yoke is good And is tight

    How much is a little play? How many miles?

    Can be done in chassis but back box has to come down to do it. At that point, might as well rebuild it or at least do a reman back box. Depending on age and mileage, might just try to wait and do a reman trans if you can. If the output bearings have wear, you can be sure all the others do too. Is it noisy?

    No bearing on any truck is made to last past 1 million miles. Unless maybe the micro blu,, but not sure.

    Yup as said . Back section has to come off. Then you might as well go through it and do anything else that needs attention. This is a little tricky and recommended for a good gear shop.

    Maybe even consider a reman trans if it has high miles and coming out for clutch anyway??

    Our transmissions are 18spds but it’s a similar box full of Timex parts screwed on the back. We don’t mess with Aux sections anymore. Exchange reman transmission. Hang a new clutch on it when it goes in and thats the end of it for a half million miles or so. It’s hardly worth doing an Aux section, you’ll soon be back in there at the Main anyway, so you’re really just doubling the labor and downtime and buying a reman transmission the hard way.

    Swaan ..... sounds like you know me!!!!!Thanks for all the opinions. I bought this truck 9. Yrs ago @. 875k Had trans done @ 500k.I had to put in a reman @ 1.2 mil. I can only guess the original owner didn’t drive it right.I noticed tail shaft play a few yrs after installing trans. Rebuilt drive line a few yrs back.Im thinking the bad yoke/ u-joints caused it. I went through a couple u joints before doing it right. Meanwhile it hasn’t gotten any worse.Ive put a1 mil on trans changed oil once @ about 350 k. Oil still looks like new.Ill inspect top side while it’s out.I suspect I can run this trans a good while longer. The tail shaft play isn’t noticeable while driving.Driveline has held together well.I just wondered if bearing could be changed easily after removing yoke.

    Just a note.Im not a big fan of rebuilt or reman anything.Simply because they check parts and reuse whatever is within acceptable specs.Of course a lot of things are so expensive you really have no other choice.Just like a tire is only as good as it’s flat spot.Because I’ve seen so many reman trans go bad, I can see trading the good one I have for a rebuilt and getting the same life out of both.A good example is the rears on my truck are original.I planned on doing them both soon after buying Truck.Here I am 9 yrs later only changed 2 wheel seals bearings were fine. 2.1 mil miles.Go figure.I used to throw money at my trucks trying to buy peace of mind only to sometimes cause more aggravation. I won’t touch a Truck that had a Driver in with a bunch of new parts . It’s obviously been abused.

    Well if you are really thrifty and talented you can machine down the spacer between the output shaft bearings. After removing the yoke and extension housing the rear bearing can be removed and the spacer between the bearings. Take .010 off of it an put it back in with the old nut. Check it and then maybe a little more. When you like it put in the new seal and nut.
    I am not recommending that but it should work if the bearings look good. Understand not being a reman fan. A company here sent their 2012 truck to the dealer with transmission problems. We had previously replaced the cooler and related fluids as they were one. The reman has at least 3/16 yoke side play and the it is tight on the shaft. Customer is not concerned. What ever.

    Thank you I’ll look into that. It’s really not much play. I noticed it at probably about 200 k. Idiot that installed Trans left oil plug out.I should have checked myself except my back was out at time. I ran 200 miles. Noticed it when fueling - half empty. 1 month later started leaking real bad. They left a couple bolts loose on bell housing. Had trans pulled and installed right.Another$800 labor luckily the original Shop reimbursed me. And that’s why I do all I can to stay out of shop.
