Eagle Posted June 30, 2015 Posted June 30, 2015 Does anyone happen to know what size bolts are used for the upper mounts on the rear shocks? I need to replace the shocks on the '01 XJ I bought for my daughter. The underside has more rust than any vehicle should ever see, so I'm anticipating that I'm going to snap at least a couple of them and have to drill and retap. I'd like to have the new bolts available before I start. Thanks.
mik666 Posted June 30, 2015 Posted June 30, 2015 not sure on the bolts but sure sounds like you should apply the ole acetone/atf for a few days to hopefully help the situation a bit

Eagle Posted June 30, 2015 Author Posted June 30, 2015 http://www.naxja.org/forum/showthread.php?t=1050368 Thank you. I would have guessed metric -- and I would have guessed 8mm. And I would have been wrong. That's why I asked.
Strokermjcomanche Posted June 30, 2015 Posted June 30, 2015 As far as the bolts coming out in one piece like you said some(if not all) will probably break . I prefer instead of drilling and tapping for new bolt holes , using a air hammer and punch the old welded nuts out and install new nutserts or using a nut held on the backside of the crossmember with a wrench an tighten the bolt . I just did this on my 99 Xj
Strokermjcomanche Posted June 30, 2015 Posted June 30, 2015 http://www.naxja.org/forum/showthread.php?t=1042527 Unless 01 is different , I used a piece of masking tape over top of the nut with a 13 mm wrench ( if you need more length I interlocked and taped a 14mm wrench to the 13mm wrench ) and fished the nut with the wrench in the access hole of the upper part of Pete's picture . But as the guy in the link did, he fished the bolt up through the same access hole and let the thread dangle . I've tried to find a better link , but so far this is what I've found . This is to get a better idea .
wutangwisdom Posted June 30, 2015 Posted June 30, 2015 not sure on the size of the actual bolt but once you figure that out you might as well just install bar pin eliminators that way you don't have to deal with those 2 bolts ever again. Also look for a company call Fastenal they are huge nation wide chain and they have/can get any kind of fastener and much more if you don't have one nearby I could always get a certain size bolt and mail it to ya I work right next door to a Fastenal
Automan2164 Posted June 30, 2015 Posted June 30, 2015 If you spend some time under there, you can see that the top end is pretty wrenchable. I soaked mine for a week, and with very delicate 1/4 turns out, 1/8 turns back in, ended up coming out. My cousin's XJ wasn't so lucky. I just took an air hammer with a pointed tip. A quick zap in the middle pops the nuts off, then like Adam said, tape the nut to the closed end of a wrench, and fish it up there. Rob
Jeep Driver Posted June 30, 2015 Posted June 30, 2015 Snap the bolt off, drill out to accept a larger bolt. Fish bolt down from top, use lock washer. I made up my own bar-pin eliminators in about 20 minutes with some 3/16x1.5 bar stock. Zap it with an impact. Use MJ stock rear shocks. Never look back.
Eagle Posted June 30, 2015 Author Posted June 30, 2015 What I don't like about the bar pin eliminators is that the result is the upper and lower shock mounts being at 90 degrees to one another. That has to be hard on the shock.
HOrnbrod Posted July 1, 2015 Posted July 1, 2015 Eagle, why do you say they are 90* to one another? Same orientation as with a bar pin.
wutangwisdom Posted July 1, 2015 Posted July 1, 2015 BPE in that pic looks too snug to me just my opinion did you make those? they look more like front shock BPE

wutangwisdom Posted July 1, 2015 Posted July 1, 2015 still like my sway bar links as BPE don't squish the bushing like those ones stock mj shocks fit on 01 cherokee?
Crash Posted July 1, 2015 Posted July 1, 2015 Front shocks from XJ are the same as MJ. Rear MJ shocks are eye-to-eye mounting vs XJ lower eye, top is bar pin. You can press in a bar pin or make, buy use a bar pin elim. And hornbrod, What they were trying to say is that the sway bar mount as a BPE turns the head/bushing 90 degrees from factory mounting. Which in theory puts torsional force on the shock as it moves since the lower mount faces the same way.
wutangwisdom Posted July 1, 2015 Posted July 1, 2015 well sorry not sway bar links that was a typo. The brackets that hold a rear sway bar to the axle bracket off an XJ

It never occurred to me to use a sway bay mount as a shock BPE. Apples and oranges.........
Pete M Posted July 1, 2015 Posted July 1, 2015 Thanks for clarifying Crash, understand. It never occurred to me to use a sway bay mount as a shock BPE. Apples and oranges......... that's what I used. :D
wutangwisdom Posted July 1, 2015 Posted July 1, 2015 they are more rugged then the ones you buy for bend you over do you dry prices and they are usually throwaway parts on a off road rig
Eagle Posted July 1, 2015 Author Posted July 1, 2015 Eagle, why do you say they are 90* to one another? Same orientation as with a bar pin. Not the way Pete did it, with XJ rear sway bar mounts.
