Hey guys and gals. I just bought a '98 disc brake rear for my '87 Z and am looking for advice as to what I schould do before I slap it in. I am aware I will at the least fabricate something for the e- brake cables. Also It was advertised as a "locking" rear, and there is an electrical plug on the top of the housing that I suspect is the locking solenoid connection, can anybody help confim this? And if so, which wire is pos/neg and do I wire a full 12 volts and switch to it? If I replace the front seal, will I have to pop the cover? These are a few questions I have, any help will will be appreciated.

1st, you gotta get her ta lay off the booze and drugs and then teach her to back up slowly as you penatra... er, eh,, Wrong thread!!

Sorry about that!!

He, He, please carry-on....................

I know, I know, I'm off work and the WEEKEND has started!!

Will the E-brake cables from the '98 work by any chance? I'm pretty sure the plug is from a speed sensor.

If you're going from drum to disc rear brakes you need a different master cylinder and proportioning valve.

Good Luck!

Yes the cables will work... they will even snap into the underbody anchor clips.

As for the 'locking' differential, you will only know for sure by opening up the cover. I highly doubt that it has a locking differential in it. It would be a complete waste of money and most assuredly will help with the distruction of other internal weak components. And if it does... it will either be a Detroit Locker or a Lock-Right.

The electral connection is, as 72Tugboat states, the connection for the exciter of the ABS braking and Traction Control systems (either a three or four channel system).

You dont need to pull the cover to do a pinion seal... but if you have never done one, I would recommend you take it to someone that has. A simple mistake on the reassembly in concern to the pinion bearing pre-load... will cost you hundreds later.

Thanks for the info, I'll put it to good use. As for pdq67, brother, what were you thinking?:yes:

4th gen rear is wider, no? Might cause wheel fitment issues.

About 3.5" wider, but I will let you know once I measure it myself. I will be buying new wheels in the future and will compensate with offset. What I did want to know is how to tell if it is a locker once I remove the cover, what should I look for?

I mean, HECK, it DID say, "Rehabbing a REAREND"!!

He, he!!

So you gotta teach her to do better, imho!

If that were truly the case, I'd switch to a larger rear with less issues! Big girls need love too!

Big girl rearends!!

That I know full well about too!

Big rearends like the old Olds and such..

He, He!!!

Locker? It should have a limted slip unit. I can't expain, I'd need to show you pics.

You will need different offset F&R wheels and you might not like the looks of that.

We are sure gonna miss Freddie!!
