Mopar 2" Lift - driveshaft carrier bearing spacer needed?

[tysongladiator]

I have been running a 3.5" front / 2" rear kit on mine, and I blew out the bearings on the rear diff running a stock driveshaft w/out a bearing spacer.. probably about 20k miles before the pitting on the races sounded like rocks in a box.

Got the bearings replaced and immediately installed the drop spacer. Obviously, not the same as a 2" lift, but the rockjock spacer is only 80 bucks, and anyone with a drill press could make one out of bar stock for much cheaper.. Id go ahead and put one on anyways, its cheap insurance.

Was it your pinion bearing? If so, that may or may not have been caused by the driveshaft and/or carrier bearing spacer confusion. The rear pinion bearings are starting to be an issue no matter whether you have a lift or it's stock. The factory bearings are ball bearings which become loose and come apart. It may happen sooner or later. Who knows when. This is the reason why companies like Trailforged offer an aftermarket/upgrade bearing and race from Timkin for the rear pinion. The replacement are roller bearings instead of the stock ball bearings.

I did a youtube video on the rear pinion bearings as well. A few of the shops that I associate with in different states are starting to stock the new bearings and whenever someone has an issue, they're replacing them.
