[dodge68charger]

How tight do i tighten the bolts to compress the rubber bushings on the rear shackles that hold the leaf springs up

It's actually 35 foot lbs for the Coronet/Charger according to the 1968 Dodge service manual.

Only reason it sparked a memory is I just replaced the rubber shackle bushings on my '68 coronet. It also says in the manual to hand tighten the shackle nuts, drop the car to full weight on wheels, then tigten the nuts to the specified torque

@Propwash @dodge68charger any unforeseen circumstances get in the way of swapping these out? Previous owner added an additional metal strip at the bottom of each leafsprings set to keep the car from sagging. Wondering if that'll affect anything on the replacement.

New springs are a straight swap, unless you go with a super-stock or other racing type (they're different than stock length). Getting the front of the spring unbolted can be a doozy sometimes...It's usually easiest to remove the spring with the front hanger attached (four bolts to the frame) that way you can break apart that big monster front spring-eye bolt on the workbench. Right and left springs are different so keep track of that when you get your new ones. Since you're going to be there it's a very good idea to get new U-bolts as well, rather than re-using the originals. (And just fyi, sometimes tagging onto these old threads limits the traffic that will see your post, you generally get more responses by starting a new thread)..

Using stock type parts will also dictate what the torque should be but using anything other than stock type parts isn't recommended.....

Some time back I remember reading about an aftermarket kit that was in Mopar Action or other Mopar rag that said the kit was probably one of the best kits out there for an upgrade but can't remember who was selling them....

I m sorry to bump this 10+ year old thread
I m changing my bushing on my leaf spring i just want to be sure i m understanding each part properly
the pivot bolt is the one under the back seat of the car where the front of the leaf spring goes?
the rear hanger bolt is the one on the rear frame the car?
and the shackle bolt is the one that goes in the leaf spring at the back right?
I just want to be sure i ve understood every part properly since english isnt my native language
thanks in advance
