Rusted U-Bolts

As i was inspecting for rust on my recently purchased cj i noticed the worst rusted area were the u-bolts at the leaf spring/axle. Actually the nuts and washers are the most rusted. I looked on Quadritec and found a new set of u-bolts with nuts and washers for around $60. Not too bad a price. My question is, what is the best way to get the rusted nut and washers off. Most are so badly rusted that they are pealing in layers. I dont think i could get a socket wrench on them. Should i just cut the u-bolt in half with a cutting wheel? Also, do i have to jack the jeep up if i only do one u-bolt at a time? Thanks.

Get whatever socket fits tight and beat it on with a hammer then get your breaker bar and get after it. Those old rusty ubolts will snap no problem.

Don't spend 60 bucks on U-bolts when you're more than likely to buy a lift kit in the near future that will have all of that new hardware included.

it actually does have a lift kit on it. i think it is like a 2" lift kit. not sure what brand. maybe a rancho because that is what the shocks are. everything else looks ok. a little rust on the leaf springs. i am just worried about the u-bolts.

Just cut 'em off. No amount of PB Blaster and the world's longest "cheater bar" couldn't break the ubolts loose when I put my lift on. A few minutes with a cut off wheel in the angle grinder and they were off.

Just helped a freind pu a 4 1/2" lift on his jeep. Put it on jack stands and cut the u bolts in the center on top of the shaft with a cutter and they will fall right off. My theory is if you aren't keeping them - cut'em off.

Don't waste your time fighting to unbolt stuff that you're just going to toss in the garbage.

alright so i will cut the u-bolts off with a grinder/cutter. one last question, my drive way is gravel and i have no garage. therefore it will be a bit of a problem putting it on jack stands. i was hoping i could leave on the ground and cut one u-bolt off, install the new one, and then cut the next one off, install, etc. will this be possible or is there too much force on the bolt. if that doesnt work i suppose i will have to get some jack stands and work in the street. just dont want somebody hitting the jeep while i am underneath it.

Place a piece of 3/4" plywood under the jack stands. Just make sure you give the Jeep a good shake to make sure it's secure before heading under it. I've done this in the past on grass and it works well.

For jeeps (and every other 4wd that I would work on) I would definatley recommend the 6 Ton jack stands. The weight is not the issue. The six tons are high enough to get the jeep in the air.

Agree with MXG. 6 ton jackstands would cover you for sure. You can never have one that is too strong Jackstands For $35 you can't go wrong if you ask me.

As for the U-bolts, see if there is a spring shop around you. Alot of times they can make them for you pretty cheap. I got some made for 22 bucks for all 4.
