I installed an add a leaf on my 98 rwd a couple of months ago. They were sagging bad for a while too. I get the drive line vibration everyone talks about around 30mph goes away at 50mph.
I replaced my u joints about a year ago but I'm sure the vibration isn't good for them.

My question is the back is noticeably higher then the front. If I got some 1.75in coil spring spacers for the front would that help with my vibration at all?

Thanks

 

Why do you want to mess with the front springs when your rear springs are shot and have been band-aided with an add a leaf?

Fix the real problem - your rear springs are shot.

 

Would it be crazy to keep and add the add a leaf to a new pair of leaf springs? So I dont feel like I wasted money.

Also any recommendations on leaf springs that dont add to much lift that I wind up with another vibration problem?

Thanks

 

For a 2wd your only cheap options are to drop the crossmember and/or leaf spring shims.

Coil spacers and add a leafs are junk.
Bringing the front up would help but it is impossible to guess how much.

I have ome front coils and dorman rear leafs.
