ok folks i want to know exaclty what must be done to change my rear axle for a 4th gen, and will this help me run the wider tires?

 

im doin this for a couple reasons

1)so my z06's in the rear dont need spacers

2)for the disc brakes

 

I think there's a tech article on this.

 

 

1 fitting to connect your stock brake line to the 4th gen stuff, if you already had rear discs. New springs to keep your tires from rubbing the fenders with a load in the rear of the car.

 

well i just did this. Sooo...

i got my rear from a guy who had built it and had it on his 00 SS.

It was a direct bolt up on my car, the brake lines, fittings, everything just bolted in. The only thing that did not, was the E-brake cables, and I think ive gotten them taken care of now too, having just ordered them from my work Advance Auto. Im planning on taking pictures of the brake cables, the install of them, and waht not to show what must be done. Or at least thats my goal. This weekend she goes under the ax again for the cables, the Panhard Rod, The LCA's and the entire front steering tie rods, ball joints, etc. should be interesting. IF You do it, i strongly recommend going to Autozone, and buying the Energy Suspension Polyurathane Tie Rod End LInk kit.. its a cheap mod, but good.

The search function works well, just do a searchf or the 4th gen rear in this sub-forum and it should work well. In fact, ive gotten most of my info from here.

That's probalby the cheapest and most noticeable suspension modification for the money..

Anyways, as mentioned, it will bolt right up. Your stock shocks will work fine, your stock LCAs will bolt in (though I'd recommend new ones...or at least new bushings...it'll make things MUCH easier assuming they are 18 years old and never been changed).

I had to re-make the driver's side brake line from the caliper to the T-block. I used the stock T-block by the way that was used with the drum rear.

Your tires will stick out, and as mentioned you should get some new springs if they are old. I didn't ahve any problems with the fenders hitting the tires until I put 350lbs in the back of my car for the snow. Since then, I've taken 200lbs out because it did more harm than good. I have the stock 84k-mile WS6 springs in my car and they definitely need to be upgraded soon.

The other advantage of this mod besides the disc brakes is if you upgrade your wheels to 4th gen/vette wheels. I know it was mentioned above, but it is nice to not have to buy a second pair of spacers. I only needed to buy 2" adapters for the front wheels when I switched to 4th gen rims.

 

ok so what are these spacers, and will the wheels still stick out if i get the 4th gen wheels? i am assumin that the 4th gen axles are wider, correct?

 

yes, 4th gen axles are wider, so if you use 3rd gen wheels, they will stick out a bit (although some people like that). If you use 4th gen wheels with it, then wheels are going to be in the exact location they should be.

The axle will not help you run fatter tires. All it does is change rim offset that is required for it.

 

Here is a 3rd gen wheel on an LS1 rear,

 

thanks for the pic. kinda helps me get an idea of what i got in mind thanks again

 

well, i got my mods done this weekend. heres what i ran into.


1.) Ebrake Cables, fit like a champ, no problems,except... they seem to be not releasing entirely.. almost like they're a bit too short.. or the e-brake needs adjusting.. if it is possible. I am not too sure though. I cant figure out how to adjust the e-brake cable mechanism.

2.) Had to modify the end of the cables with a dremel tool , to make them accept the 00's ls1 ebrake hook. that was easy and only took about 10 minutes...

 

Do you have the part number for those cables? I need to get my ebrakes done since now have a manual tranny in the car.

 

sure the part number is as follows from advance auto parts:

Tru Torque P/N# C94264.

Raybestos P/N# BC94264

Wagner P/N# F130684

Bendex P/N# C1621


The Tru-Torques are the parts that I purchased. Be sure that when you order them, that you get the right ones when you pick them up. I had to order them twice, the first time one cable didnt come with a spring on it, and the other cable's hook area was too small to modify, so I ordered it a second time, and they sent me two identical cables with the springs and proper hook area for the rear drum hook. It all went on easy after that, but like i said, Ive gotta figure out how to adjust the e-brake, to allow a bit more slack, so that way i'll be able to let the rear drum ebrake release totally. Other than that, they work great.

So these are the factory rear disc brake cables off a '92 car? $18 a piece isn't bad, a new AAP just opened next to the AZ here in town I wouldn't mind having a parking brake just to have one...

EDIT: As for adjusting, there should be a nut you can loosen on the end of the cable that goes to the brake lever. Just loosen the bolt on there and the brake lines will have a little bit more slack.

 

is this adjustment nut inside the car or under the car in the tunnel?
-steve

 

Under car in the tunnel. Its "in the middle" of that brake bracket. The end of the cable that connects from the lever to the bracket is threaded on the bracket end with a bolt holding it to the bracket. The bracket I'm talking about is the one that the two brake cables had to come together to.

Let me know if you're able to get it working right, and if you could, post a picture of the bracket so I could compare it to mine. I've heard some cables not working with certain brackets. If our brackets are the same and you can get those cables working, I'll be picking up a set.

 

ok i will, I havent had time to work on her yet.. probably wont until saturday morning at the earliest, working 2 jobs takes most of my time up now a days.

Bad news on the longer ebrake cable that Ed listed. Napa has also discontinued the longer cables. So Part number UBP 94597 is no longer an option.

Now, since i work at advance, I am going to see if we can order this part tonight, direct from Bendex. Its possible, but it means ill have to pay shipping as well as the price of the item. No biggie though. Ill let you all know if i can and the part number and prices if its available, but I wont know for a couple of days if it is or is not.

Thanks
-setve

 

good news.. i was able to order the cables from advance.. they are bendix cables though. cost me 16.95 plus 5.00 shipping each. not terrible.. only thing is it takes 7-10 days to get them.. so now i play the waiting game. I bet it will be better than the other cables i have.. because of the fact that they are longer ones. Ive got the part number and what not from advance at the house and will post it all up here once i get themon the car and have a confermationt hat it worked better than the others.

does anyone know if there is a way to have 3rd gen wheels on a 4th gen rear and have them not stick out

 

Sure...

Create some spacers that take space out, instead of putting space in.

You'll be a rich man. There's LOTS of applications in the world at large for such a thing.

 

Sofakingdom,

Have you been reading Twain and Shakespeare again?

what e-brake cables with a 96 rear hmm?

 

2 of the finest oservers and recorders of the Human Condition ever born!!

 

Stock '91-'92 rear disc brake cables.

 

check out the brake board for the correct brake part numbers for the cables.
