Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

That turned out great! Check worn spring bushings allowing the front eye to slide back and forth for the popping.

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

Thanks, my springs are all new. Pretty sure its a TRE (which was also new) that is popping and clanking. Just need to get under there and get greasy and retorque stuff and give her a good shakedown. Spoiled by all this interior stuff and staying cleaner than clean!

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

Did you use poly bushings or rubber on the springs/shackles?
Did you install crossover steering? I have crossover steering and it will put lateral torque on the spring hangers/shackles which could cause a noise if not properly torqued.

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

I never use poly, not a fan of poly bushings. But really, the springs were new less than a year ago, maybe 3k miles or so since I've been working on it more than driving it. Standard 4x4 steering, not crossover.

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

I know you have been down on the frame, be sure to check the mounting bolts for the steering box, cracks usually happen there. Also the wonderful GM thin stamped metal adjusting sleeve for the tie rod and the drag link can be a culprit because of the design and if they are bent will move. I hope you get it figured out.

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

Off topic to the rattles and pops got the final piece of my interior done, bezel back in and about complete finally (except for a couple USB plug in ports and things like that)

Originally got a single Din radio, but after realizing that I would have to hack up my dash and everything else I was exploring other options. Not wanting to just mount a radio 'somewhere' just to have one I figured after all the money I already spend on interior why not go with a nice radio, so I got the retrosound hermosa radio. I am extremely pleased with that decision, everything about the kit down to the boxes is top notch. I mostly listen to music through my phone anyways, and it uses blue tooth so pretty cool to not have wires running all over the place getting wrapped up in the shifter etc. Plus you can answer calls and all that fancy crap as well!





Looks sorta factory, is all digital, has USB, 2 AUX, and sub outputs on the back, also bought a USB/Aux port that will mount into the dash with a little flip cover to charge stuff, or use to play tunes. I have installed a LOT of radios, and while it wasn't hard, it was definitely involved! I picked up a scorsche (sp?) adapter for the stock harness which converted all the wires to modern color codes which simplified install greatly.

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

Thanks glad it helped you out. I know when I first started to research it everyone just does build threads like all the info is gospel and you should already know how everything works and goes together. Very minimal info about people doing 4x4 conversions, what parts are needed etc. Best way to get it done is just get to it and go to work!

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

Another option for music is a headphone jack to RCA straight into a amp. I have that in my truck works great.

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

What did you do with headliner? I didn't think it was possible to get them in or out without back window or windshield out. Why don't you like poly bushings? Looking great!

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

Anything is possible! I had everything out when I first took the headliner out, meaning seats and everything. When I put it back in, I had the seats in so it definately did not fit. I ended up just folding it like a taco (carefully) and it did crease some and I'm sure the fiberboard thing that IS the headliner cracked some, but once its up and pinched between the trim pieces I smoothed it all out and you would never know. Then just having a good awl to punch through it to find the screw holes for the trim.

As for the poly, the cummins vibrates enough as it is I didn't want super stiff poly bushings making everything else more teeth rattling.

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

Been a little while, slight updates.

Was at the local junkyard a couple weeks back and spyed a steering gear box that had some fresh paint, like fresh rebuild paint, so i yanked it to find out it was a reman box that must have been fresh before they threw in the towel and junked the truck! So I put that in my truck along with a new (another used) Jeep XJ steering shaft and well...no more pop bang rattle in the front end.

Now heres my gripe. When I got my steering components original, meaning TRE and tie rod etc, I went with MOOG stuff. All new because I had nothing...I didnt look back in my thread but its been what? less than a year? maybe 2-3K miles and literally the TRE at the pitman arm and steering knuckle were thrashed. I remember the boots falling down almost immediately and not holding grease so that was part of it. This time around I went with autozone junk and right out of the gate the quality was surprisingly better. The taper was tighter, they torqued properly. The grease fittings screwed right in, no struggle like MOOG, the boots were strapped on to the joint end and took grease like normal...I bet they were cheaper too. So first pull out of the driveway and holy crap what a difference! Steering is tight and responsive and doesnt pop when I turn anymore. No more rattle and clank in the front end either.

So thats my story and I'm stickin with it

Well that's a sad story. I always thought moog was a top quality brand. They must be outsourcing china junk like everyone else.

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

A few years ago I heard Moog had been baught out. Around that time I had a lot of moog ball joint and tie rod end failures. I switched to XRF at that time. I've heard Moog has their stuff together now but I'm leary to go back. Although, I did get Moog chassis saver tie rod ends for my 40 Ford recently. Hopefully they last....

Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

I shoulda known when the boots were all goofed up. They would hardly stay put with no grease and not installed, once you greased them they would pop off the knuckle and shrink up. I don't know what happenened but either way thats the last I will spring for them!
