Leaf & shock bolt sizes on 99 XJ
Greetings, finally going to get around to changing the leaf springs and rear shocks on my 99 XJ and figured I'd ask some questions related to OEM bolts on my truck.
I've been drenching the upper bolts on the rear shocks with PB Blaster as well as the front and rear bolts that hold the leafs, along with the u bolts that fasten to the rear axel in order soften the blow. I've used a breaker bar on the leaf bolts and I know that both front/rear leaf bolts are now slightly loosened, but in the event that I break or have to cut off either of those leaf bolts, can someone please tell me the sizes for those bolts so that I can buy them prior to the job.
Also, my big concern are the upper bolts on the rear shocks, I tried loosening them with an extension and they feel like they may be slightly stripped, I'd definately like to buy all four upper shock bolts in anticipation of shearing those. Can someone tell me the size of those (head, length, and thread size), don't want to have to be in the middle of the job & drop what I'm doing to then go and look for the right bolts. This way if I have to drill and tap em I can simply replace, thanks in advance.

We are in the same boat. Beginning tomorrow, I'm switching to the angle grinder and will begin cutting. Began removing my rear floor and now have access to those stubborn rear shock bolts.

I did not cut the floor pan. Drilled the bolt out, then dropped a new bolt with washer down from the top using the holes that are a few inches away at edge of panel.

I've seen that guys do that Steve by guiding the new bolt to the hole with a thin wire. So what size is the original bolt for those rear shocks and what size did you use to replace them?

I ordered a new set of oem leaf spring bolts from teamcherokee.com. Be warned, they're like $50. I had to cut a few of mine because the bushing sleeve was rust-welded to the bolts.
For the rear shock bolts, don't cut the floor or drill them out! Get an air chisel from harbor freight for like $10-$15 and use that to punch out the captive nut. It's then very easy to fish new hardware in from the top. This technique took me like 20-30 minutes and was a hell of a lot easier than cutting/drilling. I'm sorry but I don't remember the size, I'll check back in if I find it.

No, I do not. I bought this expecting problems with the rear shock. It came with bolts.

[COLOR="red"]That price is crazy. I'm going to Lowe's and buy grade 8 bolts. /COLOR]

They are not OEM, but I source suspension bolts (leaf springs and control arm) from NAPA. Usually in stock, $5 - $9 each.

I believe they are M8 1.25 (pretty standard), and their length I don't recall exactly, but I wanna say 30mm. Maybe a little less. (they are so common, that you can usually get little packs of them at any auto parts store). And the ones sold in little packs will have the flange shoulder and will typically be class 10.9 (metric equivalent to grade 8).
