Thread: Locker in P38

Want me to pull the rear diff apart, or is there a simpler way to tell?

Cheers, Paul.

Sorry Paul thought it was written on the diff but i cannot remember. I will search the ARB site and get back to you. Do you know if the early 95 diffs changed later in the year models. I thought they all stayed the same. Andy would probably know. Nothing like trying to solve a problem from half way around the world
Cheers,

Here's what I understand... someone please correct me if I've got it wrong.

It's all to do with 2W-Traction Control versus 4W-TC:

• 95-98 models (TC on rear only) have a 2-pin diff at front and 4-pin diff at rear.
• 99+ models have 4-pin diffs front and rear, and TC front and rear.

The RD128 suits the front for 95-98 models.

The RD138 suits the rear for all P38's, and front for 99+ models.

Cheers, Paul.

Thanks Paul

If you had a 95-98 model & wanted to fit a rear locker only, would it not be better to swap the front & rear diffs around, then update the old front (now rear) to a locker?

That way you end up with a stronger 4 pin front diff.

Now that is thinking!
When you buy a locker does it come with the 4 pin centre though?
How much will this cost me to do this upgrade?

All ARB lockers are 4 pin AFAIK.

Sounds like a great idea. When i get back from the states i will see what was done and what i have at my disposal. Thanks Scouse!
