I seem to remember reading in Guinn’s book that Penske had axle failures when that was tried.

Ok so I am looking in Wayne Guin's book and it seems that original JL8 rears were mounted with one U-bolt and T-bolts on the other side of the spring pad.......As for the HD service rear/racing version does anyone know how they were mounted? Basically I was going to copy the JL8 style mount for ease or brake line routing at this point. Did you trans am boys double up on the U-bolts or did the factory stuff hang in there just fine?

So no one I talked to had a definitive answer for that endplay so we settled on a touch over zero. It's what the competition manual suggested and the posi I have is shimmed tight so it should wear in a touch more....the calipers sit square over the rotors so I guess we'll see how it flys (or stops I guess).

--sending c-clips to get hardened

--the book talks about shot peening axles and studs....I used Moser stuff....it's pretty beefy so I'm hoping it'll hang in there. The car won't see any 4 hr endurance contests so Im thinking it's good.

--Moser axle flanges are about 1/8" thicker than the 12 bolt stuff which threw some curve balls at the JL8/J56 parking brake setup....it clears, but it's CLOSE!.......I may take a little off the parking brake shoes to help this.


So yea! That's where this thing is at............HAPPY NEW YEAR EVERYONE!!!

So this thing is still moving forward....plenty of help from my buddy who did most of the welding and grinding but here is where I'm at.....everything lined up without having to make spacers like the "Untold Secrets" book talks about.....And the caliper bracket to rotor surface measurement is right in spec too!! Working on the parking brake cable mounting now.

Here are some pics

Yea-I'll shoot some this weekend.

So....interesting tidbit here...I downloaded and printed the "chassis preparation manual" that jon mello posted up here (thanks jon btw)......they list the axle end play spec as ZERO to .015".......ZERO!....playin' with fire there once that whole deal heats up to racing temp.

I know..I know........way over analyzing  but I just thought that was kinda cool

Trans-Am Camaros / JL8/J56 or HD Service rear end setup question
« on: September 24, 2017, 02:29:58 PM »
Hello all......I'm putting together a disc brake rear end with the "fixed mount" J56 corvette style calipers. I'm shooting for .005" axle end play......I know this will require custom c-clip thickness which will change as the posi clutches wear..I'm trying to get an idea of how often this will need to be adjusted or reset on a road car. I figured if anyone would know it would be someone here. Any guesses?

-So from what I've read, Penske would change his rear end every race so no issue here...

-the lesser funded guys...How often was this checked/changed? Was the pad knock back tolerable enough to make it thru a season?

-what about the JL8 owners.....I can't see this being a "dealer service" adjustment every other oil change or anything right?

Ok thanks guys.....Tyler

Hey--are these things really worth all that much? I have one that I was just going to use in a 302 hot rod build....is that not a good idea?
