it seems challenging to replace a rear in your driveway

actually, it was VERY easy to do

i jacked the rear of the car up and put jackstands under it

took off the wheels, set up the jack under the left side control arm

took off the sway bar

removed the shocks from the rear

removed the lower control arm

slowly lowered the jack

spring came out with little to no force

repeated this for the other side

when i got it out from underneath, i took off the torque arm and put it on the new rear

then i put the new rear underneath

i jacked it up on one side and put the lower control arm underneath it didnt bolt it up yet though

then i bolted the shock on and put the spring in

jacked it up and then tightened the LCA

repeated this for the other side

the only thing i didnt do was hook up a parking brake cable

i need to know which one to get and how to hook it up

brakes went on without a problem

oh yeah, the rear is a 3.23/disc/posi from a 94 Z28

so if anyone needs help with their 4th gen rear swap, you can ask me

 

Is the rear end any wider than the 3rd gen? If so, how much?

I assume you didn't have to have anything relocated, like spring perches or anything did you?

 

nope

except for the parking brake cable its a 100% no modification bolt in

the wheels stick out a little more on either side, but it doesnt look bad

 

Actually if you own an early model thirdgen like my 82 the brake line connectors are a slightly different size. But its no a big deal to fix that problem.

 

what kinda parking brake cable do i need to buy??

help me because i have no clue

 

pfft dont even use a e-brake, mines doesnt even work

 

ehhhhh i kinda need to considering its a manual tranny

 

o, well then, yes, you will need it, haha

 

Go to the dealer and get a set of e-brake cables for a 91 or 92 f-body with rear disc brakes and you should be all set. Check your adjuster though...does it look like this?

 

wow

ya?

;-) Just messin'

 

I agree with ebmiller, the later F-bodies (90-92) used identical rear disc brakes as the 93 to 97 4th gens. Those parts will work.

its a very simple job, i did it in my driveway by myself in a few hours. pretty simple, i modified my 9 bolt PBR brakes to work on the 4th gen rear though.

 

Oh yeah, if you're a cheap ***, I've got a set of used e-brake cables lying around if you want them. I won't need them for a while.

Ed, sportin' 1LEs now

 

does anybody know if the 1LE setup that spohn will be selling will be bolt up to a fourth gen rear, more specifically a '98 up?

 

When I ordered my E-brake cables I got teh 92 Camaro 1st design cables. tehy have a 1st and 2nd design so make sure you get the right ones.

 

Why won't the original cables work. The replacements alomst look too long judging from the picture in this thread.

 

cuz it had a drum rear
the new rear is a disc

 

where is the ebrake adjuster, exactly? Im looking into doing this swap when i swap out the auto for a 5-spd. How does one go about fitting a 4th gn rear into an 83z? What mods are required and can i do it myself? Do i need a lot of expensive tools i dont have? Thanks

Interesting... I put a 91 or 92 rear into my 83, the cables that came with the rear just hooked right up to my adjuster, it hardly even needed a different adjustment from where the drums had been set. I think the brakes are the same on the late 3rd gen and 4th gen rears but I don't know that for sure. No mods were required except that I got the last few inches of steel line (metric) off the 91-92 car, and cut the same amoutn off the SAE line in my 83, and spliced the metric end onto the SAE line with a flare union.

 

wm_sorg:
Those lines are Earl's braided lines and seem to be a bit longer than the stockers. Also, I haven't installed the brake line keeper on the strut and that's why it's floppin' around out there.

black 83Z:
Look at my picture of the adjuster. It's located in the driveshaft tunnel above the driveshaft almost directly under the e-brake handle. This is an '88, I think the '91-'92s are different somehow.The 4th gen rear will bolt right in but you may have some brake line issues and you will definitely have to change out your master cylinder and prop valves. I would just because they're 20 years old. You should only need basic hand tools. DO a search on "rearend swap".

RB83L69:
Did you install a drum 4th gen rear? I wouldn't think disc/drum cables would be the same. Good job on the splicing!

 

You don't have to change you master cyluinder and prop valves. For disc brake cars the rear-end is almost a direct swap all you need is an adaptor for the brake line, The E-brake cables all you need is 92 CAmaro 1st design cables annd you will be all set.

The only way you would need a new master cylinder is if your was already bad.

The only way you would need a new prop valve is if your car was originally drum.

 

No, I put a 91-92 disk brake rear in my formerly drum car.

It was not even necessary to swap the MC or prop valve, they seem to work perfectly. Balance is excellent front to rear.

Parking brake cables are the same on the car, the part on the rear is of course different. I simply hooked the rear's cables (they came with the rear) to the part that stays with the car, and they hooked right up as if they were meant to go there. Absolutely interchangeable in every detail as far as I could tell.

 

If I stay with my stock drums (will these work) will it be a direct bolt on?

 

Do you have any pictures of what it looks like with the 4th gen rear in? I am concerned about how far out the tires will be if I decide to do that as well.

 

i am also in the middle of installing a 4th gen rear...and im home free except fot the e brake cables...i installed a jegster torque arm and i think that completely covers my e brake junction...im screwed!! lol

 

will the extra width of the rear end improve handling? i figured it might since overall 3-4 inches wider or something. have you tested it out yet?

 

its about 1.5 inches wider on both sides...you can feel the extra width...it feels better....the gears are great and DAMN the disc brakes rock!!! it woulda cost me more to get the gears and put them in my drum rear than this did...i couldnt be happier..

 

So where do I get this cable????
I need one!!
Do I have to go to the scrap yard?
If so what's the difference between the 1st and the 2nd design?

 

i have a 83 and i'd like to see a picture with the rear in, how far does it stick out on the side. i live in the country and im concerned about throwing rocks at my car with the wider tires/axle. a picture would do me wonders
