Lin and Listers;
I have rebuilt 5 rear ends with the Lempert rear gear sets and I
have found that although the original bearing were a good quality the pinion
bearings are a good candidate for replacement. Pinion bearings are under a
lot more stress and RPM than carrier bearings. They are under a pre-load,
are much smaller than the larger ring gear carrier bearings and travel at 4
times the speed. With new pinion bearings installed the pinion rotates as
smooth as silk instead of slightly rough. I now recommend this for any rear
ends I rebuild. Just my 2 cents worth but hope it helps...Russ Bamsey
