My 2021 JLU build thread

[RhinoJLU]

I looked for probably a little over 2 hours for them to no avail, I think the name is on the tone ring I’m just going to have to pull the rotor off to find out.
Real slick set up tone ring presses on the outside of the unit bearing, bracket blocks off factory wheel speed sensor hole and holds the jeep one.

I used 2” spacers and they were 8x6.5-8x170

I thought about going to 8x6.5 in the front just for ease of finding a spare wheel and tire anywhere on the trail but for ease of replacement parts and keeping things “factory” I kept the unit bearing knowing I can go just about anywhere and get one.

Any idea what the WMS front and rear including the spacers? Also what backspace are you running?

4.5” of back spacing on the rims

I believe the Dana 60 is 72” I have .5” spacers to clear the steering arm so that puts me at 73” in the front.

The 14 bolt is 68” with the 2” spacers puts me at 72” in the rear.

Sounds reasonable. Lockers?

Arb air lockers front and rear

Cool thanks. Didn’t even know you can do .5 inch spacers.

For the stock sport axles with 37s? I felt like they were sufficient could still stop quick if needed

OK thanks for the feedback. I've always been curious about when you should upgrade the non-HD brakes on the Sport, but if you can safely/effectively run 37s on them, I think that's pretty good. Really appreciate it and thanks for sharing your build with us. Enjoy!

It’s not much wider than I was on stock axles with 2” spacers and the 37s

Yeah drove to Arizona/utah/Colorado through the mountains and hills and never felt brakes were lacking.

Was it the Rocksolidfab kit for the front D60? That’s what I’m using on my build.

Was it the Rocksolidfab time RK gs for the front D60? That’s what I’m using on my build.

This? .... question... how much for the pair.. and how long did it take for you to get them? thanks!

The kit is $400 but I have not ordered yet. It will be a while before I’m to that point because I’m slowly piecing together this axle build over the next 2-3 years.

Wait... those two tone rings are $400 ??

Yup! Comes with abs sensor brackets too though. Not much competition in that market to keep pricing down I suppose. Most people with tons on JLs just buy aftermarket crate axles.

Yes this is what I am running in the front

Beats disassembling the unit bearings and swapping the internal tone rings when one fails or drilling the side of the knuckle to position the wheel speed sensor like I’ve seen. Can easily transfer from one unit bearing to the next.

Holy crap... $400... I much rather spend a bit more and buy a mini lathe and fabricate my own tone rings... LOL..

BTW... I am looking at other options... I know Spicer makes front Dana 60 52 tooth Tone rings because how else do they make ready to install Dana 60 Axles for the JL ??..

Here... I found this document...

https://spicer.com.co/wp-content/uploads/2021/04/catalogo-tecnico-performance-2021.pdf

Notice Item # 51 on page 38 ... the tone ring..

Page 39 describes it as:

Google shows the "Dana Spicer 2023673" as a 52 tooth tone ring.. for $72 a piece, and Ebay
has them for $62 and free shipping.

https://downtofab.com/products/spicer-2023673

However, these front hub assemblies seem to be completely different from the
2005+ Dana 60 Superduty ... so, yeah.. that idea is a dead end... but I wanted to
post this information anyway so others do not waste time with this alternative.. LOL
