When replacing final drive do I need new bearings?

The shop that is doing all of my work says that I need new bearings for my transmission and LSD due to needing to press it, which apparently breaks the ball bearings. I'm wondering if it is absolutely necessary to break them because 200 dollars is a lot to spend on bearings when the whole tranny brand new is only 1700

ken,
some people need new bearings, some don't...
it depends on the state of your bearings at the time of installation and also how careful the person pressing out the bearing is...
i have been thru 6 FD installs and have only experienced 1 tranny that needed new bearings

if you do, you only need to replace the ones on the counter shaft

hmmmm.....well if the people at ATS say i don't need new bearings....then i dunno why the mech says i do....oh well i will ahve ATS talk to him tomorrow to find out what his reasoning is. I trust the mech...but if I can save that 200 for something else I would do that.
imo even if the bearings can be saved.. $200 would be a small price to do now rather than have it fail even a year later. that would mean at that time you would have to pay labor to r&r the whole thing.
i think you already clocked a good 20k on the tranny and which would still be considered new. but i still think since its already out might as well replace it now.

Yeah I know that i better be safe then sorry. But the guys at ATS say that I can make sure that they are good or not. He said I should be able to tell. I dunno. The guy works on trannies and diffs for a living. But like I said I also trust the mech. So we'll just have to see what's up....if not can i sell used bearings LOL
i'm sure the baring is still good. and it might be good after the install. but i think were he's (mech) coming from is why instal used bearings. would be a shame if it goes bad a few down the road.
The ball bearings on the LSD may be damaged during removal. The bearing puller contacts the outside race and applies force to the inside race across the *****. Installation applies force only to the inside race. I would hate to do all that work and later learn that a bearing was bad.
The two differential bearings (p/n 91005-P80-E31) should cost about $70 for the pair.
On a side note:
The older style, tapered roller differential bearings (you most likely do not have these) can be easily removed without damage, but the clearance setup during installation is hideous.

he's not changing the lsd, only the final drive
that being said, at minimum, I would change both mainshaft bearings, and one bearing on the countershaft, the one closest to the nut, also change the seal on the mainshaft
IMO $200 is not much, instead of doing it later on
just make sure to use only OEM parts

OK so at 28K on the clock the new FD and ATS parts have been installed......the mech says i only have one salvagable bearing
Even my buddy at Acura laughed when I asked if I need to replace them. He said they should last at least 80K. WHat makes them go bad?
The bearings are $300.......I'm getting the old ones back to have some friends inspect them. I really don't see how i could toast bearings this fast when the car was never abusively driven. I don't understand it.
ATS guys tell me not to replace.....Acura tells me not to replace......I dunno.....i understand taking precautionary measures....but I think this might be overkill.
300 dollars is a lot .....and if I'm spending that much I want to know for sure that those bearings are toast and why they are toast. I mean is there a certain way to put in this FD without busting the bearings up? I mean I don't think they were toast from me driving em. Sorry about the rant......at this point I just can't justify it. I'm putting all my trust in the mechanic. But everyone with tons of tranny knowledge and experience are telling me these things last the life of the tranny.

Hey not for nothing... but for 200 buck I would rather spend that money and put a new bearing in there and have a piece of mind, rather then you having problems after the install and having to go BACK into the tranny once agian.

IMHO if you have more than 100K miles on your bearings, I say its a good idea to change them. if you also have owned your car since mile 000001, and its had its intervals on tranny fluid changes, bro, you are FINE. I have seen stock trannys go and go and go on and on and on when maintained properly. If you are the 2md, 3rd or who knows which owner, and doubt its history... and you have more than 100K I say change them. Dig? Mechanics make a spiff on replacing parts. If it were something that ordinarily fails, I say change it. It isnt. If you have to change your diff out, change the bearings. I would rather spend that 200 on either and ATS 1st gear (3.077), a new 3-4 sychro set, a new clutch or lightweight flywheel or labor if in fact you cant do it yourself. good luck
...ps when you pull the diff, it pops out. yes, indeed it pulls right OUT. maybe about 20 lbs of effort and yep, you got it it comes right out. the bolts on the diff are REVERSE THREAD... so remember that. when you take off the diff bolts, the ring gear comes right off... yes, indeed... right off over the diff. the bearings on the diff arent even effected!!! someone here can feel free to disagree, but I have seen this job done and I was shocked at how easy it in fact is. you need air to remove the 14mm rev thread diff bolts, loctite to put them back, tq to about 25-30ft lbs if I remember (refer to the helms) and then the diff drops back in like a bowling ball...
right into its place. its really cool to see how awesome the tranny is on the inside...
good times. the counter shaft is another story, but I'll leave that to the 'experts'. I look forward to putting the ATS kit in my GSR.

See thats the thing......28K i'm the only owner....never abused....now they are telling me all my bearings are bad but one......so that includes some of the diff bearings. But those have never been touched, nor should they have been damaged during removal....so really i don't know wtf is going on here.
Everyone with experience is telling me 80K....100K......so how did all my bearing just turn to **** by themsleves. Was it installer error? I will have macro shots of the bearings for you guys to look at. I'm really not feeling so good about this.
