I don't remember the size, but I got mine at lowes. They had them there. Are both stuck, or just one? When I was doing mine, i just couldn't get them out,so I used a wrench and a floorjack to get them the rest of the way out.... it was time consuming but effective.

 

Hey, bro. I saw the link you put up of the bolt for the front leaf spring. Is it the same exact bolt as the OEM for the front bolt of the rear leaf spring?
Also, is it the same bolt as the rear bolts for the rear leaf spring?

I tried to lift my jeep last weekend and ran into the same problem and Im just looking for OEM bolts now before I cut the spring out. thanks

 

They are the same. Try burning out the bushings. I did not need to cut the bolts, just needed some mapp gas. Far cheaper than new bolts.

 

You may try backing it out as far as it will come getting a helper to get a pry bar behind the head and pry back at it against the "frame" as you try to back it out.. ALways works for me.

 

Ultimately how i got mine out when I did mine. After getting it so far out just put vicegrips on it and pull and twist until they come out.

 

I usually get mine about half out then they spin,, Thats when I get someone with a prybar to pry back while i ratchet, or if I am alone..ill use pliers to wrap behind the bolt head and try to pry it out as I turn a wrench.

 

I had to cut drill and tap mine...can't remember the size. Not looking forward to doing springs on my new XJ.

 

I think someone needs to start a thread strictly for nut and bolt thread sizes and lengths. Ive spent hours on here looking for various bolt sizes (and usually come up with nothing).
Will be putting a 3" RC lift soon and wanna get new leaf bolts before I even start. Thanks for the info guys!

 

I believe they are m14, 2.00pitch, and 120mm long (with the stub nose). I got mine from a local hardware store they gave 120mm long without the stub nose and they were a little to long.

When I replaced my rear leafs the sleeves were stuck on the bolts. I used a cut off wheel to cut the spring eye off then use a utility knife to take the rubber part of the bushing off. Was able to heat up and spread the sleeve and then bolt came right out. Had a sawzall handy but I thought this way might be easier. One of the welded nuts on the front eye broke off and I had to cut the bottom of the bracket out (not the unibody rail). Found a ton of pb blaster soaked dirt when I opened it up.
