Differential Bearing .... please read
I know that this problem is starting to get common... i took my car to my mechanic today to have him check it out... he says theres nothing major wrong with the trans, i dont need to get it fixed, what will happen if i dont get the diff bearing fixed?( i'm still not sure that that is the problem, the whining i get is when i am at a stop, and it doesnt happen constantly) also is 1st gear whine while accelerating normal or not???? no one seems to have a definitive answer on this... i have searched so please dont tell me to search, thanks in advance

I am not a transmission expert, but have gone through 4 transmission total so I have quite a bit of experience. I had my transmission rebuilt because of gear whine. If you are sure it's coming from the transmission, it is not normal and means the bearings are getting worn out. I suggest replacing all of them. I have all of the bearings you need with only 10,000 miles on them and in perfect condition. They seriously look brand new. I will sell them to you for $100 if you are interested. I posted them a while back in the for sale forum, but never got a response. Pm me.

It wouldnt surprise me when the bearings go bad. Its a very expensive repair. Given the depreciation of the car and the cost of the repair, you might as well just get rid of the car. This is not a flame but how I sincerely feel.

Of the four transmissions I have gone through, the only time I ever heard gear whine was when my bearings went bad. Just my experience.

A first gear whine is not enough evidence to think your bearings are bad.

If the tranny is truely bad, just get a junkyard one and install it. Selling a $7000-8000 car because it's tranny is going bad is entirely a stupid thing to do. An entire tranny rebuild only cost $1100-1500. A junkyard tranny with install shouldn't run more than $800.''
As for the 1st gear whine, my 96 has done it since I bought the car back in Feb of 1999 with 30K miles.
If you're hearing a "whirring" sound while the car is in neutral, I believe that you throw out bearing could be bad. It happens.

Lets see, $1000 repair on a car that KBB's for $5000-8000, to me thats ground to loose the car. I tried to hang out to the max as long as I could (wait a min, I still have it, its parked outside havent been touched in over 2 months) but after 3 transmissions and getting screwed I said screw it.
For the second part it wouldnt be your throw out bearing seeing as the TO bearing should only contact the spinning pressure plate when the clutch is depressed. A little bit of noise while idling in neutral with clutch out is normal- the clutch, pressure plate, input shaft are still spinning.

nismo - are you confident you know the source of the whine at idle? transmission/clutch, more engine perhaps...
I'd worry if I started getting noticable whining in 2nd gear, and found slightly too much play in the axle as noted in checking in other posts...plus if I had a sweat by where it's documented to check for a tranny oil leak according to this issue.
I'm curious, to those who've experienced...when 2nd gear and others start to whine from the diff bearings issue, can you feel anything in the shifter accordingly, like where if you'd neutral drop it would go away?

By the way I replaced all the bearings in an '87 maxima. The diff bearings were VERY bad. It made a grind grind noise as the car would roll. The bearing replacement is not as hard as you might think 40,000 miles later when I sold it the trans was still quiet.
I have also replaced all the bearings in an '86 rx-7 but doubt that is of much interest on this forum.

thanx for all ur replys, my car is currently at the aamco transmission center and is having an external diagnostic done and i will find out whats wrong, i have not had any second gear whine at all... so i dont know if it is the diff bearings, but it may be somethign else, and while i still have this extended warranty i want to make sure i get the trans fixed asap.... thanx again for all ur replies

Your car was a rare case and given your past driving record, many of your problems could be related to the way you drove it, your ACT clutch, and possibly the way you repaired it. You're neither a certified Nissan tech nor a certified ASE tech. It does take schooling and experience to fix and set up bearings.

i have the problem now.as we speak my cars in the shop getting the tranny rebuilt.my car would whine in 1st gear and reverse,but only for a second or two.it was like a whining/grinding noise.it'll get worse over time and eventually your tranny will begin to leak,guaranteed.

yup looks like my tranny is going under the knife once the warranty co gives the okay kinda sux to know i'll be without my car for 1-2 weeks but i am happy that it'll be driving better and no whinin!

I expect to rebuild the trans on my '96 when I take it out to put in a clutch. Maybe I'll put in a limited slip diff this time =)
