YJ Rear Disk Brake upgrade

I would like to put disk stoppers on the YJ rears. I would like to do it without buying an expensive kit. Is there any parts from another vehicle that can be modified eaisly to work on the YJ rears?

Yep, get a '95-'01 Ford 8.8 rear axle from an Explorer & get disc brakes & MUCH better rear axle.

Don't waste any money (beyond gear lube costs) on a Dana turdy-five.

Yep, same bolt pattern. I finished the install on my 8.8 a few weeks back. The disc brakes are a real bonus. I did the swap for the heavier axle, gears and locker and got the disc brakes in the bargain. You can do a complete 8.8 swap for no more than it would cost you to do a disc brake upgrade on your stock axles....if you shop around for the axle and fab the stuff yourself.

If you can do it that cheap and disc brakes is all you're after that's a good deal.

But it's still a Turdy Five, but now with disk brakes that will hold your axles in for a while.

Rear DS u-joint can be whatever you want, since the 8.8 uses a plate type yoke system, whatever plate is used dictates the u-joint size. Plates are easy to get and not expensive. NAPA also has conversion u-joints (I use one), where it's one size on one cross and another on the other cross.

Bolt pattern is the same. Width is close enough not to care. Brake hose from the YJ connects to the 8.8 fine. All that is needed is relocating spring perches and shock tabs. Both of those are easy jobs.

My goal is too get rid od the drum brakes. For what I do with my YJ, the rearend is fine until it grenades. I'm looking tor the cheapest way to get disc brakes. The drum brakes get full of mud, the adjusters stop working. If I go the XJ which sounds to be the eaisest way, is there a way to connect the E-brake. I put new hardware and cylinders and shoes and they still suck. I like to do what I do as close to stock as possible. I believe in the best cheap way. Not necessairly cheap parts in quality, just in price. I want to be able to re-license it some day if necessary. I haul it everywhere now.

Thanks for your comments.
Happy Wheelin'

What all would you need to grab from the grand xj? Going to replacing my frame soon so I figure do it now while it's all apart- I'd love to do the 8.8 but I have no welding/fab skills whatsoever- but if anyone wants to help me do the 8.8 swap there's beer, pizza, and a small purse as a thank you- haha

NO, not XJ, it's the ZJ's (mid-'94 -'98) that have the disc brakes.

You've got a 92, you may want to think about the proportioning valve from a 96+ XJ or possibly any ZJ, not sure... a search here or on the XJ forum will help you out a lot.

Anyways, it's the 1st-Gen Grand Cherokees (ZJ) that you want. All XJ's were drum rears unless some1 along the way did the upgrade to ZJ discs. Also, make sure that the ZJ donor axle is a D35 and not the D44-A. Another thing (which I'm fairly certain won't matter to you with the YJ) is that all ZJ's are ABS. Well, maybe one more thing - you may want to also do a search to see if the parking brake cable will be a problem attaching to the ZJ brakes...

ZJ's will fit what you're asking for. Cheap, direct fit (from a D35), and easy. And around here, about $49 including the ridiculous NYS "environmental fee" they impose on the u-pull.

You could also just upgrade the front discs, Grand 44 knuckles, and skip the rear. "Wait until it grenades" are other words for "waste money on something I'm going to toss later anyway".
