I think the diff is no good but only under load. Is there a way to check the clutches for slippage without ripping the cover off?

Jack up the driver's rear wheel, take the parking brake off, and put the transmission in neutral. Then, using a torque wrench, see how much force is required to cause the driver's wheel to turn. And LSD in good condition will take better than 50ft-lb of torque before the wheel will turn.The car makes it possible, but the driver makes it happen.

Post results if you will
Going to try mine this week. Its a fresh LSD the is smooth and locks predictably and smoothly.

About 25-30ftlbs and it spins.......
I tried to pinpoint it under the car running but it only seems to have make the noise under load.Last edited by Mr.SWISS; 11-21-2011, 07:54 AM.:nice:Originally posted by 325ProjectzComment

I'll be doing this this weekend just to see how good my LSD is performing.'84 318i M10B18 147- Safari Beige

Guess I don't understand why this test is useful. Doesn't the LSD need a load to lock. So jacking up the car and doing what was said wouldn't place enough load to lock it IMO but maybe it does. Just having a hard time believing this test is really worth while. Maybe, meh

It works because one wheel is locked by it resting on the ground. So what you are measuring is how much force is required to cause the clutches to slip.
BTW: a new E30 differential should hold 65ft-lb before the clutches slip.The car makes it possible, but the driver makes it happen.

aight, I misread your post then. I'm seeing the whole rear jacked up not just one wheel. lol Thanks for the clarification Jim

That is a pretty good set of clutches. It could be better, but not worth rebuilding at this point.Originally posted by Jaxx_ View PostThe car makes it possible, but the driver makes it happen.

And to clarify the torque wrench should be measuring the torque at the axle nut and not a lug nut right?Never argue with stupid people, they will drag you down to their level and beat you with experience. -Mark TwainComment

I would think so. If you do it on a lug nut, then you are adding leverage. So 56 could possibly be 60+Ma che cazzo state dicendo? :|Comment
