Rear Upper Shock Bolts

I will be taking a torch to all four to try and expand them enough to crack the rust and help free them.

Please say a prayer for me and my TJ that we do not break off any heads. This is my DD and I am so screwed if this happens. But the old shocks are completely dead. They do pretty much nothing, the bushings are rotted out and they rattle around loose. The rear end is like riding on a buckboard. So I have to try...

If I break one of these bolt heads off I will be shooting my TJ in the (engine) head. The viewing will be on Monday with funeral to follow. Cold beer will be served.

Just soak them with pb blaster for a week and you will be fine. I wouldn't bother doing it with heat. You might blow yourself up.

If the shocks in the jeep are currently useless/dead , i would do what i did. I used a cutting saw i believe it called a recipricating saw, i cut the shock out of the way, then drilled out the ones that didnt want to come out. I remember this night mare haha! Easily fixed but a pain in the butt

Use a lot of pb blaster. When I put my lift on I broke all of the bolts for the rear shocks... Took about 8 hours over 2 days to drill them out... Good luck though. If you can wait a few days for the pb blaster to loosen them up.

I advise spraying PB blaster repeatedly for at least a week before attempting to remove bolts. In addition, heat would help but fuel tank is close by.

PB Blaster two or three times a day for over a week. No love. I know heat works. And several here have recommended it to break really bad rust. I am talking about the kind that has eaten through a lot of the exposed threads. Bad rust. I want to buy all new hardware, but I just found out that our dealership no longer has access to all the fasteners. He suggested I go to a local bolt and screw shop that they deal with. They are cool. I have bought from them before. So if I can get it, all new hardware is on the way. But if not I am afraid to break these old ones. It is my DD, so I guess I have to wait for some time.

While heat *will* work, I am afraid of the gas tank. If doing this with a torch yields results with no explosions nine out of ten times, I will be that tenth time...

The PB blaster worked great for me too. Just be sure and use it on the top of the bolt (between the frame and the tub) so it can soak down into the threads.

Have fun with this headache sucks.... Just did mine about two months ago. I tried the cutting but had little luck getting in at the right angle. I ended up bending up the shock at close to 90* so the piston would not move.

X infinity on soaking with PB blaster multiple days ahead. I just went through this and broke one of the bolts on the rears a couple of weeks ago. Thank God I had a 1" BL and could access the nuts. My neighbor and I spent a good hour swinging away with a 3# sledge and crowbar and knocked the nut off. I thought of heat, but was too scared to do it that close to the gas tank. Don't blow yourself up. Good luck my friend.

This one is worth the extra soak time. All four of my bolts were rusted to hell. Two weeks of hitting the top where the nut is and down below on the threads with pb and they all broke free. You definitely do not want to snap one of those bolts, especially if this is a daily driver. It's a bear of a spot to have to drill bolts out. If they do break, you may just want to turn your torch loose on your gas tank. Good luck.

I would use Kroil instead... PB works OK, but no where near as good as Kroil.

Great responses so far, guys. Thanks!

RE:Kroil

Can you get it at NAPA, O'Reilly or AutoZone? That is all we have in my small town...

Don't think so. I always get mine at an industrial hardware store. I'm pretty sure gun stores have it too.

Use a 50/50 mixture of ATF and acetone.
You'll never use Pb blaster again. I can't say the same for kroil, never used it.
