65 Coronet: Upgrading the Rear Suspension in Your Old Mopar

The 65 Coronet’s rear suspension was in terrible need of an overhaul. In this video, I disassemble the rear springs and shock plates, clean and paint, and reinstall the 8 3/4 with new Eaton springs, bushings, bolts, shackles, and QA1 Billet shocks.

[@BigfootsnMopars]

Looks great. I think I over tightened my bolts on my leaf springs in the Satellite and didn’t let it rest on the ground before tightening. Might be the source of my vibration issues.

[@JustMoparJoe]

Maybe a pinion angle thing. Especially if driveshaft is balanced and straight.

[@johnelliott7375]

Keep on keeping on, Mr. JMJ! I know what you mean I had to put a door on a Cat skid steer, with all the goodies in the heat today. Wiper and washer,. A/C, heat, double thick tempered safety glass, defrost, switch the wiring harness, washer pump and tank, wiper motor, latch, safety switch for the door , and new seals. You got the picture, nothing like modern top of the line equipment.

I like the attention of the details that you are doing to make it look as good as possible without going to town on a rotisserie off the frame restoration. I think you are doing a great job, regardless of the critics, only one thing that I am not a fan of is zip ties, but I am only a opinion buddy. Great evening and great job. TTYL

Thanks John. I cut the zip ties after forming the line, and got rid of the old line. Now it’s a new shiny piece in the car!

We have the same housing sitting at the bottom of the front porch steps 65 Coronet. My brother unloaded it there. Now I get to move It. 😂

[@JustMoparJoe]

Man, if you get tired of it, I’ll take it off your hands! 😂

[@rod426]

Great video, Joe! I'd re-use the "u" bolts for the rear too or get new ones. Aftermarket I'd throw those away. Everyone has a opinion on how to but the whole rear and springs together but in the end, it's what works and works for ya. If the owner doesn't like the car, I'm sure I'd take it off his hands.

[@JustMoparJoe]

Thanks buddy. He’s thrilled about it. I do like the stock u bolts. These were as nice as any I’ve seen. I will recheck torque.

[@440Nichole]

turned out beautifully Joe ! i did my own on my '66 Belvedere . has an Eaton 3.55 truetrac on super stock springs . it's on my Banner pic if you want to take a look thanks.

[@JustMoparJoe]

Definitely will! Thanks for the support!

[@ninjapumkin]

Nice 😁. Question, the front shackles, I noticed the passenger/driver side leaf to shackle bolts. I always thought the bolt head was on inside to not allow it to walk out if the nut fell off. I could be wrong

[@JustMoparJoe]

Thanks brother. Thats a nice way of doing it. As long as the bolts are tight, I don’t think it matters. A little lock tight doesn’t hurt! 😂

[@ninjapumkin]

@@JustMoparJoe no worries. When I pulled mine out the bolts were opposite direction. I know their castle nuts so it would be pretty tough for them to loosen up

[@cjm5002]

This is one of the videos ive been really excited to see and you definitely delivered! I was super skeptical about that rust paint on the housing but you totally sold me now. That looks super good. One of the things I mock the hell out of is guys who do a great paint job, put on nice wheels and tires, build a sick engine/trans combo, and then leave the springs/axle all crusty looking like crap. Amazing work as always dude! I do have a question and/or request though. Have you done or plan to try to do any reconditioning of parts with acid dip or electrolysis? Ive been considering giving it a try myself with my front suspension parts, especially the springs and control arms. And now covering it with that rust paint you use.

[@JustMoparJoe]

Thanks CJM. I haven’t used the electrolysis. I believe rust oleum makes a gel that will turn the rusty stuff black. Then you rinse and can paint it. I’ve used the permatex rust converter before in areas, then sanded, primed and painted over it. The Devil is definitely in the details.

[@johnelliott7375]

Looking good Joe , but to be honest I don't like the passenger side brake line , it doesn't look like it will allow for caliper movement

I need to do a full rebuild on the rearend lines. I think it was a poorly designed kit, that the owner stuck in to get rid of the drums. Thanks buddy

[@sparlin88]

Looks GREAT Joe !!! Is the underside of car and rear axle and sprongs painted Satin Black 2 parts mix ? Thanks

Thanks buddy. That’s an air Jack. Or air bumper Jack. It’s older than I am. Part of Dads collection.

[@doacarnage]

I would not re-use those old u-bolts. I have custom 5/8 u-bolts made up at local spring shop, I love overkill. A trick I learned with cleaning things up is to spray the rusty stuff with diluted muriatic acid, then pressure wash after 10 or 15 min. all the rust will come off and there will be no need for wire wheel.

[@JustMoparJoe]

Very nice. I had similar results with the rust oleum gel that comes in the squirt bottle. U bolts are working well.

[@Umwee63]

Nice Joe. Looking for a 400 4bbl intake, have any you wanna part with ? Also 16" coined dually wheels.

[@thomasward4505]

Plus Joe that X case on the eight and three-quarter will break really easy, definitely not made for any kind of power

[@JustMoparJoe]

I wasn’t aware. I’m certain it will last in this heavy 4 door on the skinny stock wheels and tires. I think it’s a nice rearend for what it is. I have a few 489 cases that can be used if need be.

Thanks Thomas. He wants to drive this car home at 75-85 mph. I know when they first came out, interstates were just becoming a thing. I like the 2.76 in my challenger currently, but I do like driving over 75 a lot. As far as I know, he will keep the short 205 tires on here.

[@perrykocherhans2475]

What paint did you use?

[@JustMoparJoe]

That was Eastwood’s rust encapsulator. Same as I sprayed the bottom with. I really like it. You can topcoat it, or leave it as is.

[@jerryfarmer5989]

Well you could take a hammer and "alter" the roll over on the new bolts. Plus it never a good idea to re-use U-bolts. Length easy with a death wheel. And I tend to lean more to the DANA's, 60's that is and of course the Shur grip. But a little paint n shine at least you can tell someone did something.

[@JustMoparJoe]

Jerry, you can’t prove your u bolt theory. Especially in a car that had the easiest life it could have. This is nicer underneath than it was from the factory. If you don’t like my work, don’t let the door hit you where the good Lord split ya!
