Ball diff's

[lofty2332]

Having a nightmare with the rear diff on my Cat 2000, I either have to run it fully tightened because as soon as I loosen it is too loose. If I race with them fully tightened up and I going to cause any damage?

Also why would they been working loose? I am guessing the ball bearing are old (new ones on order from a bearing specialist) its a nightmare with Schumacher not manufacturing parts.

I must have rebuilt this diff about 5 times always with the same problem
