How do you loosen the front end of the leaf springs when changing springs? As the bushings have a metal sleeve that rusts to the bolts, and will eventually tear the nut off the frame before letting go...

 

I use kroil

 

Kroil. Also tighten the bolt before trying to loosen it.

 

I recently replaced mine on my 99 with 151k and the only trouble i had was the rust not letting the bolt slide all the way out once loose. If you look at your frame there will be holes there where you can shine a light through and see the welded nut, also use that hole to spray it down with penatrating oil.
