I think bad roads are wrecking my suspension

Well just when I had all suspension noises fixed, it is back again.

Took a trip through the horrible roads of DC last night and then a trip to a client this morning that takes me over a shit road that's ripped up. I tried to go slow and take it easy.

Now I am hearing the clunk clunk clunk again. Right rear, again.

I suspect that the IRS parts I've installed in the rear plus the stiffer springs and shocks are wreaking havoc on the OEM parts and bushings. Meaning that the bad road conditions are destroying my suspension which is exacerbated or made possible by all the suspension stiffening components.

I've been through this 4-5 times now. I'm confident a shop can fix it but what do i do then? It's just gonna come back again isn't it?

Here I was a few days ago planning out my spring mods, but if a good solution doesn't present itself, I may be looking for a new car. I can't have this happening to me 20X. I don't have the know how to fix stuff myself and I don't have the time to get it fixed every time this shit happens.

Maybe I've dug my own grave with this suspension thing. Unfortunately not all roads are good and I have no choice but to go on some of these roads. I wanted a Mustang that would handle better but I now fear I have invited more trouble than I bargained for.

What do I do now?

Unfortunately you can't have your cake and eat it too. A firm suspension is good around corners and on the track, but a soft suspension handles bad roads more comfortably. Maybe some progressive springs might help? Or firmer springs, but softer struts?

The only time I've ever heard a clunk was when the upper rear shock mounting bolts weren't torqued down. It was noticeable immediately, so I didn't get much further than out of the driveway before fixing.

The only significant force increase from your springs in dampers will be to that mount and the spring mount of the body. Check it out.

I've had several issues.

Last time I had this clunk noise - the shop said they found the BMR toe rod to be cockeyed which caused it to hit something at the car moved up and down. Must've happened during the alignment according to them.

The second time I had creaking noises, from the right front and right rear. In the right rear it proved to be a noisy UCA bushing. They replaced the right UCA piece completely and were able to lubricate the left side to make the noises go away. It's been fine for a while since then.

It wasn't until driving on these bad roads that I noticed a problem.

I hear it -

1. When I left off the brake from a stop to hit the gas
2. I hit a bump
3. I come to a stop from being in a higher gear
4. Sometimes hear noises from the area when I shut off the car and put in park. How this could be happening I don't know.

I don't think it matters what parts I installed or from what brand. It's not installed incorrectly. This is happening because of Ford and how they designed the car, and the roads they we have here in Maryland DC area. Warped, ripped up. Complete crap. But there's nothing they can do nothing they can do. The winters wreak havoc on the roads.

I think any part I install, I will eventually have noises occur. The OEM parts that are there are not made for this IMO after what I've gone through.

I may be looking for a new car soon it looks like. But I'm not going to give up just yet. I'm going to talk to the guys at the shop and try to figure out why this stuff keeps happening. If is unavoidable then I guess I've wasted my money and I just deal with it or trade it in and buy a new ride.

Sorry you're going through this. I too live in MD, although near Baltimore.

My suspension is completely stock (other than the Steeda G-Trac brace and the IRS braces) and I have no problems or creaks with 33,000 miles on the car.

I know you don't want to hear it but if the car was fine when it was stock, and now, after modifying all of the OEM bits and piece's with stiffer bits and piece's, it's creaking and making noises, how is that Ford's fault? I'm just not seeing the connection.

This sounds like a driveline issue, not suspension. I'd go through all your diff bushings.

I'm not saying it's Ford's fault. Just saying the OEM pieces are not meant to be paired with aftermarket pieces, thus causing the OEM parts to fail or detoriate.

It could be, but I doubt because I hear it also when I am not even on the throttle. Could be both maybe. Who knows at this point, I am cursed.

The diff will move around a bunch when you hit a bump, particularly since you have the cradle stabilized via the CB005. Those bushings are soft.

Check the rear upper shock mounts. I got my clunk from there after breaking one. OEM part # FR3Z18A161A is $20-30 and installation is super easy and less than 30 minutes. Alternatively, Steeda makes a pair of billet mounts for $180 after discount.

That is an interesting point. You could be onto something

I would be very pleased if it turned out to be the diff rocking .
