I just thought I would get a thread going on junkyard upgrades to get this info all in the one place for people building their XJs on the cheap. Maybe if enough people post the XJ compatible junkyard parts they know about this could become a sticky.
WJ front LCA's
-same length as stock XJ LCA's but have a bend for clearance of wider tires
-slightly thicker steel than XJ LCA's and made of boxed square tubing instead of channel
-can be modded to fit XJ by cutting down the bushings to fit in the XJ's LCA pockets
WJ rear LCA's
-don't have the tire clearance bend but are 2” longer than stock XJ LCA's
- slightly thicker steel than XJ LCA's and made of boxed square tubing instead of channel
-can be modded to fit XJ by cutting down the bushings to fit in the XJ's LCA pockets
ZJ
V8 coils give 1” of lift on a XJ
gastank skid can be made to fit a 97+ XJ
rear discs can be swapped onto a c-clip D35 or corp 8.25
V8 tierod is much stronger than the XJs and is a direct swap.
Early to mid 90s ford crown vic rear disc brakes are almost a direct swap to an XJ d44 or non c-clip d35. All that is needed to bolt them up is a spacer that goes between the outer bearing retainer and outer bearing seal to make up the difference in thickness between the caliper bracket and drum bracket to give the proper bearing preload. On the XJ d44 you can use the factory outer retainer for a TJ Rubicon d44 (mopar pn 1-05083678AA) after it is redrilled to correct axle flange bolt pattern. On the non c-clip d35 a custom spacer must be fabbed up. A 1/4” tall section of 2.5” od tubing with a ~.120 wall thickness should work.
The following vehicles rear leaf packs can be used in combination w/ an XJs mainleaf to lift the rear end (cut the eyes off of the mainleafs). Trial and error will determine how much lift.
Dakota leafs
S10 leafs
MJ leafs
XJ leafs
YJ rear brake line is 3” longer than the XJ's and is a direct swap.
