I have an automatic 1993 240 (non turbo) with 120K miles and the bearing(s) need to be changed inside the rear axle. You can hear some VERY small 'rolling' noise and feel a very small vibration. I went to my garage and they first changed the bearing of the drive shaft and it reduced noise/vibration by about 80%. But with the car on the hoist and with the rear wheel spinning at 50 mph, using a screwdriver to listen to each wheel and read axle, I could clearly hear noise. And when driving teh car after, I could hear and feel it. But like I said, it is only 20% of what it was prior to changing the bearing of the drive shaft. It seems to me pretty clear that this is the problem. The garage wants 0 to change teh bearings inside the rear axle. My question is, can I wait? I mean, if I don't get the repair done, will I most likely be fine for another 25K miles? Also, is 0 on the high side? I would appreciate your input on this situation. Thank you.
