Rear driveline carrier bearing drop

[Splenda]

Nothing wrong with asking for peoples’ experiences before buying and installing parts. That’s all this is about.

Wow, I just realized that you have started 23 threads in 28 days. I think that may be a record!

Just take a look up under there. There are two bolts that go straight up through the carrier bearing support into the bottom of the bed. You just put a spacer between the support and the bed and put in longer bolts. It's pretty simple. I never had any vibration, but I installed the spacer when I installed my lift.

I installed a carrier bearing drop spacer on a previous vehicle (not Jeep) and yeah it’s super easy. Super simple. It’s more a question of what size are people using and why. I noticed such a wide range of aftermarket spacer sizes, and hadn’t seen much talk about “use 1.5” drop with a 4.5” lift” for example. That’s all.
Still waiting on parts and ordering things so chatting about the details is just part of the hobby.

Stalk much?

It's literally right there under your picture on the left.

You can kind of calculate by figuring the amount of lift you are doing. That lift is going to be at the differential end of the driveshaft. The carrier bearing is sort of in the middle, so you would want the drop spacer to be around half of the lift amount. You can calculate it with some geometry, but I'm not sure it's that critical.

Have a 4" lift with the Rock Jock spacer. No issues.

Nah, not looking for an actual mathematical formula. More like a ballpark figure is good enough. I noticed some lift kits come with a carrier bearing drop spacer, like Rock Krawler 4.5”, and some don’t.

Good to know. Thank you

I would do the spacer. You start leaning your rear housing back and it affects coil spring seats, shock clearance, trac bar bushing bind and such.

That’s what I was wondering about tilting the rear housing back. Yeah. Don’t want things to get weird.

4.5” lift with Rock Jock spacer. Got it for free, otherwise I probably wouldn’t have one. I just laid on my back and used my knee to hold up the DS while bolting the spacer in.

You can place an angle finder on the shaft before lift, then determine what thickness is needed after, without creating too much of an angle at the tcase.

Here is the RK spacer with the RK 4.5 inch rear springs. Puts the two piece driveshaft directly in line.

Thanks for the pic
