ARB Locker on my 45PU (1 Viewer)

[Steinar]

I'm about to order a ARB locker for my front axel, I have aussie locker in the rear (works great). I have been searching and found out that I need RD33, but.... what about the bearings.

"Late model 50.00mm [1.969"] ID carrier bearings (e.g., from FJ/HJ80
model) must be used. This will also improve bearing life."

Anyone who has any experience ? partnumber ? From a 80 axel: with or without locker ?

Check out the new RD142. I think it's replacing the RD33.

The RD124 replaced the RD08 which was a 45mm carrier bearing semi-float application. The RD142 replaces the RD33 which replaced the RD02 which was the 45mm full-float application. When Toyota went with a 50mm carrier bearing, ARB had to make the 4 different lockers. Rather than produce 4 lockers (RD02, RD08, RD33, RD124 and RD142) ARB thinned the heard to the RD42 and RD124, the flip side is you have to use the 50mm carrier bearings for all applications.

You'll need:

Timken: 32010X
Koyo: 32010XU
Toyota: 90366-50024
Nachi: 50KB831LT & 50KB801

Thx very much...........

90366-50024 is used in Century GZG50 and Lexus LS400/430 and GS300/430/460

It's not used in the FJ/HDJ80 series. It seems like several Toy diff bearings can be used.....

The RD124 replaced the RD08 which was a 45mm carrier bearing semi-float application. The RD33 replaced the RD02 which was the 44mm full-float application.

So the RD124 is for the semi-float? I just ordered two lockers from IPOR for my 45 and was told that I needed the RD124 front and rear. I have a full-floating rear.

I hope I'm getting the right stuff.

I'm afraid the RD124 fit's axels with "C- clip" That means semi-float.......

Thanks. I need to verify that I'm getting the right stuff.

I didn't catch the difference in 124 and 142 when reading though this thread quickly. I did mention RD142 in my post above.

RD142 spec sheet The RD142 is the new version of the RD33.

Your getting semi-float/c-clip lockers, however they will work just fine in a full-float front or rear application. You can put the RD08/RD124 or the RD02/RD33/RD142 in a front, but only an RD08/RD124 on the rear of a semi-float. Theoretically the RD02/33/142 is a tad stronger than the RD08/RD124 but its really a non-issue overall. Locktite the cross-shaft retainer pin into the case and call it good.

Correct, sorry I mis-interpreted what we were talking about. You are correct, the RD142 is the replacement for the RD33 and features a new one piece case and is possible "timed" (havn't heard yet). I attended an ARB tech seminar in November where this was discussed but I'll have to dig through my notes for details.

it appears that the difference is the THRUST BLOCK 110102 used to keep the shafts from sliding inward too much.

also the spiders are different.

What difference are you referring too? Semi-Float models versus Full-Float models? The cases are different as well. The newer models feature the clip style housings and timed gearing too.
