My harness/headlight upgrade is NICE but the rear disc conversion is REAL NICE.

 

How much longer are the ZJ Studs then he XJ studs?

 

A little bit. About the thickness of the caliper bracket longer.

 

Do I need any Axle seals or Bushings.

 

It wouldn't hurt to go ahead & replace the outer axle shaft bearing & seals while you have it all apart.
I think the ZJ studs have 5-7 more threads to them.

 

I need the Wheel studs too. Can I tap them out of the ZJ at the Bone Yard ? Or do I need to REMOVE the AXLE shaft to get to them???

 

Yes, along with the longer caliper bracket mounting bolts.

 

What size should the longer Caliper bolts be??

 

Same as a 94 to 98 ZJ.

 

I am in the middle of this conversion ,Now what do I do with the ABS sensors ???? Do I need to get them from a ZJ???

 

Oh Man ,I broke both Brake lines at the Wheel Cylinders .

 

I had to buy new Brake Lines . The backing Plate I bought from the 98 ZJ did not have to be opened up in the middle. They fit right on,every thing bolted right up and works very nice.The only problem I had was Braking the Brake lines 2 of the Spider Gears came out of the Diff. They took some time to get back in right . I am glad I did this Conversion, I was driving for Months with out Rear Brakes . Its good to have 4 Brakes again. Thank GOD.

 

I was reading that some ZJ's came with a dana 44a and I was wondering since I have a 87 pioneer with a dana 44 rear would the disc brake conversion be a direct swap more or less? would I still have to make any modifications to the bearing retainer etc?

 

Hey guys so I'm looking to convert a 94 grand cherokee zj Laredo dana 35 with drum brakes to disk and I need to know if A) can you just directly swap it to disk back plate? B)is there a way to keep the abs system? C) is there anything else I would need to to do the swap?
