80's Diplomat front end parts? - 05/19/10 05:47 AM

I am about to rebuilt my whole front end on my 83' Diplomat police package.
I just want to know if there are any other additional parts that I have to get aside from the usual front ends pitman, idler, ties and rods, upper/lower control arm bushings,shocks, etc.

Thank you.

Mopar Muscle did a buildup on a mid 80s Dippy Cop car about 5 years ago. Check their site. They may have info.

If it won't keep an alignment, I've read hard service early 80s AHBs can crack the k-member. Just something to keep in mind.

Make sure you do the bushings on the sway bar too

Recently bought all the parts for my 74. If memory serves I got upper/lower ball joints, inner/outer tie rod ends, upper/lower control arm bushings, sway bar bushing kit and the strut rod bushings. I decided to wait on the pitman and idler arm until I tear into it and decide at that point whether they need doing.

How far are you going? I rebuilt the front end on my Fifth Avenue (same chasis) a couple years ago and went through everything. Wound up pulling the K out and completely stripping it.

- solid aluminum K frame bushings (from Firm Feel)
- upper and lower control arm bushings
- upper and lower ball joints
- idler arm
- pitman arm
- torsion bar bushings
- pivot cushion bushings (from Firm Feel)
- stage 1 gear box (from Steer and Gear)
- KYB shocks
- sway bar bushings

All of the bushings and ball joints I was able to get through Moog, with the exception of the pivot cushion bushings. The dealers were picked clean of them a few years ago; luckily Firm Feel makes their own.

While you have it apart, the solid K biscuits are definitely a worthwhile upgrade.

The KYB shocks are a bit harsh. Patrick Grossman replaced his KYB shocks with Monroe Sensa-tracs and gives them a great review. I'll be looking into a pair for the front in a of couple weeks here.

If you are having and issue with keeping it alignment, odds are the K frame has sagged. It's a common issue, but really isn't too big of a deal. You can shim the upper control arm mounts with washers to correct this.

The nuts on the lower control arm bolts are tack welded in place. You'll need to torch them off if you want to remove the lower control arms. Be careful not to damage the K.

Torsion bar bushings were and absolute bear to pull off of the bars. Couldn't use heat on the bars either since they're spring steel. I think I used a cut-off wheel to do the job, but be EXTREMELY careful not to score the bars.

I'm sure I'll think of something else after posting.

Good luck....
