Calling all 242h swappers!!!!

I need to know what the length of the rear DS is for a 242hd. I have everything else but the rear shaft. Also any advice on setting preload on my Dana 30? I have to swap the yolk for the Double carden shaft. It should go smoothly if I can get all the parts before I tear it apart.

I have this wierd clunking in my front end, when I hit the brakes it thuds, and does it again when I let off the brakes. I put on the stillen kit from kolak and it's acting like there's slop between the piston and brake pads, but I've inspected the system a few times now everything appears normal. Could it be slop in bushings pivoting the axle? Just seein if this has come up before. Thanks guys

The rear drive shaft is also a different spline count.

Yah the 242 has a 32 spline output shaft. As for the clunk, check your caliper bolts. when I did the caliper swap mine came loose after a few hundred miles. Had to tighten them down in a walmart parking lot in the rain. As far as the pinion preload, I would search. There is a really nice writeup on here, alot of pictures and details on how to do it. You will need a dial type torque wrench that reads in inch-pounds. Youll need to measure the rotational torque before you take off the old flange. Youll need to take everything off, brakes, hubs, axle shafts, to do that properly.

Get a new pinion nut bolt as well. Mine was put on and cross threaded so when I took it off it made a mess. I ended up having to pull out the differential. I was able to fix the threads with a die and thread file. Wasnt a fun two days. Some people mark the old bolt and then tighten it down on the new yoke to where it was plus a little more. Id suggest getting the factory service manual and familiarize yourself with this. The factory service manual is pretty detailed and tells you step by step how to set the preload.

TL;DR: search for the write up on setting the pinion preload and get the FSM. Replace the pinion shaft seal while your at it. Check your caliper bracket bolts.

I have a shaft seal, crush sleeve and new pinion nut ready. I can not find a rear driveshaft now. It's the last piece of the puzzle!

Thanks or the help jimmay! The front end thud has me stumped still. Brakes are all tight, everything seems as it should. If I can find a rear DS today ill be doing my swap this weekend.

Did you check your sway bar bushings? I had an XJ clunking like that, it was the sway bar wobbling around inside the bushing.
