george.bryant Posted September 23, 2006 Share Posted September 23, 2006 I did quite a big burnout lastnight (all legal location etc), and now my car is making a loud whine at certain cruise and acceleration speeds. I'm not sure if its the driveshaft or the diff whining, how would I find out? I have a R200 LSD and I was told these were just about indestructable.

johnc Posted September 23, 2006 Share Posted September 23, 2006 The driveshaft won't whine. IMHO... what's likely is that the front diff mount was damaged enough that you're getting some metal-to-metal contact in the mount. The whine you're hearing is probably normal diff whine, its just being amplified by the damaged mount. Quote Link to comment Share on other sites More sharing options...
george.bryant Posted September 24, 2006 Author Share Posted September 24, 2006 What mount do you mean...Can you show me a pic? Quote Link to comment Share on other sites More sharing options...
boodlefoof Posted September 24, 2006 Share Posted September 24, 2006 I'm not particularly familiar with the R200, but in my experience when a differential starts whining in the manner you have described the pinion bearing has gotten buggered up. Certainly look at other areas for a potential cause first so you don't pull apart the center section for nothing. Quote Link to comment Share on other sites More sharing options...
george.bryant Posted September 24, 2006 Author Share Posted September 24, 2006 OK, i'm kinda new to this. I've never had to fix any part of the drivetrain on my car. Where is the pinion bearing located? How do I check it? I'll be putting another driveshaft in when I do my manual conversion next month. But its not the driveshaft is it? Its the differential?

johnc Posted September 24, 2006 Share Posted September 24, 2006 George, You should get a copy of the factory service manual or one of the Haynes manuals for your car. The mount I mentioned above is the mount that's under the front snout of the differential and bolted to the removable crossmember. Quote Link to comment Share on other sites More sharing options...
boodlefoof Posted September 24, 2006 Share Posted September 24, 2006 The pinion bearing is actually inside the differential housing. Unless you have the appropriate tools and know-how to set up the differential it isn't an easy DIY job. Quote Link to comment Share on other sites More sharing options...
george.bryant Posted September 25, 2006 Author Share Posted September 25, 2006 I've just been to a few places around town and they said 2 1/2 hours for labour just to pull it apart. And i was told its big $$ to spend to overhaul a diff. I do have a FSM but I have no experience with dismantling a diff. I will check the oil level in it when I finish work. I'm worried, I need it fixed but I dont have a huge budget... Quote Link to comment Share on other sites More sharing options...
george.bryant Posted September 25, 2006 Author Share Posted September 25, 2006 It's full of oil still. Quote Link to comment Share on other sites More sharing options...
Phantom Posted September 25, 2006 Share Posted September 25, 2006 Before you do anything make sure that: 1) It's not really the transmission that's whining, and 2) Drive the car and make a few tight turns. If the whining goes away during the turn but is present when driving straight it is rear axle bearings. Quote Link to comment Share on other sites More sharing options...
george.bryant Posted September 26, 2006 Author Share Posted September 26, 2006 Its a automatic transmission. Lately the vehicle has been making occasional banging/cluinking noises that soudns like its coming fomr the bellhousing, i thought maybe it was the torque convertor cause If i put my put flat on the break and pump it a bit the banging/clunking stops. I will give the tight turn thing a try when I finish work today. Thanks for your suggestions. Quote Link to comment Share on other sites More sharing options...
