Mustang Forums - View Single Post - Clunking Noise sounds like rear passenger side

hmayoral · 01-31-2008, 06:21 PM

Replacing My lowers with CHE lowers not only cured my squeeks and binding noises. I realized that the clunking noise disappeared too. When I took a look at the old lower arms (only less than a year). The poly bushing fell off when i was inspecting one side. It looks like when I was driving either on uneven roads or driving up a steep drive way, the bushing were binding and was causing premature wear. I was able to spin the bushing inside and noticed wear on the end of the bolt sleeve. Even though it felt tight, it was still moving around when I was driving. The bolts had wear on the threads indicating it was banging around (hence, the clunking noise). The only way you can tell is by taking it apart and inspecting the bolt and hole. Man, that noise too was pissing me off. Until I met Steve and told me about delrin sleeve in between the poly bushing and the bolt sleeve. It looks like CHE doesn't even hold the patent on this idea. CHE had to wait for this guy that Steve had mentioned to me, that makes the custom bushing, inserts the delrin sleeve and bolt sleeve into a stack of awesome looking control arms from CHE. This Delrin piece is like indestructable, self-lubricated (no more friggen greasing) piece of plastic made by Dupont.

Below is email the Steve sent me when I had them installed.

Henry,

That's great news. Sounds like you're on your way. I have yet to have one single complaint get back to me about the CHE control arms, and particularly about them squeeking. Your detractors need to check into Delrin a bit. It's neat stuff. Hard as a rock, yet basically a plastic or nylon type material, that's easy to form. And most importantly, self-lubricating. It's made by DuPont, and I guess they spent $50 million developing it. Google "Delrin self lubricating".

So tell your friend it's a $50 million dollar piece of nylon. For that much cash, it ought to be good at something! In many racing applications, they use solid Delrin as a replacement for a rubber bushing. That's pretty stiff for a street/strip car, and polyurethane became a bit better of an idea for street applications. The CHE design uses the Delrin solely for it's self-lubricating purposes, as a bearing of sorts, and uses polyurethane for the bulk of the shock absorption. That combination is the best of both worlds. I have great hopes for it's long term increasing popularity and success. I remember in the old days of 70-81 GM F-body cars, it was pretty popular to use solid Delrin bushings to replace the rubber leaf spring bushings in hot street cars.

If you can come to the understanding that it takes care of the lubrication part, then everything else makes sense. And since it's got a very long life, and is low-friction, it should extend the life of the whole bushing assembly. And Delrin doesn't need to break in either. It's the same from beginning to end. Poly bushings with grease starts out as an ok deal, but the grease dries out and becomes sticky, and over time it will help to break down the bushing, especially if it's not synthetic grease (such as that supplied by Energy Suspension to be used to install the bushings). Not to mention that makes a huge mess. I hate working with grease. Make a deal with your buddies not to do any maintenance on the control arms for a year, and see who's hating life in a couple months, LOL.

On a positive note, I just opened my Ebay Store. The lower cost of listing parts for longer periods of time has allowed me to list a lot more parts, that are less likely to sell as often. For example, I just added 83-88 T-bird control arms. A great find for those guys, since they've been left out in the cold over time due to their rarity in the racing circles. Before, they just didn't sell often enough to warrant carrying. But now, with a lower cost of listing them, I have added them to the lineup along with a slew of other parts. The best news being that I'm now able to add packages of parts that before were sold separately. For example, I have the 79-04 Mustang adjustable uppers, and the lower control arms together for $275 shipped. Even better for the S197 crowd, I've added the adjustable upper and fixed lowers combo for just $254.95 shipped. In the short time that I've added these combo deals, I've had a lot of buyers so I guess that appeals to folks. It's also a bit easier to buy just one time instead of twice I guess, on top of being cheaper. I'll probably expand those package deals in the near future, to include axle braces and maybe even a grand package with panhard bars as well. CHE makes so many cool things for the 05's, and I can't wait to bring them to the masses.

You should definitely get the upper adjustable control arm next. Having just one upper arm really puts a lot of load on that one piece, so you should see a nice improvement with installing it. Give some serious thought to the lower control arm anti-squat brackets too. I believe they will help traction nicely, especially in a stick shift car to keep it from spinning on the shifts.

Did you say $180 to install them??? HOLY COW! Its four bolts man! If a cop gave me a violation for working on my car, I would probably use it as Charmin.

Steve, So far it's been beautiful. No noise. It feels great to cruise around now. All thanks to you. Of course you got those who think it's still breaking in. Another guy tells me " No grease fitting! Impossible. You'll regret it". Even after I let them see it. They said "no way, not a piece of nylon". Well I'm about to prove them wrong. I feel positive about this. I'm already thinking about the uppers. Just have to build up my play money (thinking about some other parts). Had to pay 180.00 to install them. It sucks have no garage. Cops up here give violations for working on street. Totally blows.
Regards
Henry

I'm loving life now.
