The KONI adjustables - Bump and Rebound

Bugeater · Jul 22, 2003

Found out this weekend at VIR my driver side KONI adjustable rebound/bump adjusters would not budge...seen to be frozen together. Before sending them back to Dodge to fix/replace, has anyone tried using WD40 or ??? to try and free them up? I'm not sure I want to force them too hard and break them.

Has anyone had problems with their adjusters?

i had the same problem on 2 of my konis on my 99 ACR, the dealer replaced them under warranty, but go quickly, i had to wait 4 months for my koni shocks to arrive....

Jim Benkovich (Minn) had this problem recently. I suggested he try a couple of squirts of diesel fuel to loosen them up. It is an excellent penetrant - far superior to WD-40 or similar canned oils. Unfortunately, I never heard back from him one way or the other.

My Penskes' rebound adjusters tend to fill up with sand, dust and grit. I usually blow the recesses out with compressed air, and/or flush them with water. The 2812 Konis have both the bump and rebound adjusters stacked in the top eye. I would think this makes them even more susceptible to getting locked together by grit between them. You might also try *very light* taps to the side of the adjusters with a drift punch and small hammer. This may help dislodge the grit. It surely beats being without shocks for 4 months...

Thanks - I wouldnt be out shocks for 4 months, just downtime of swapping them out as new ones would be on order.

Will try the diesel fuel idea. Wouldnt mind keeping everything in place since I just had Archer's guy Russ setr my car up height/alignment-wise.

BTW, did you know Dodge's list price for fronts are 900 each, and the rears are.......2,900!!! Each!!! What a joke.

The diesal and blowing with compressed air finally ended up working for me. They had to sit for a week but they eventually did move. They can be disassembled / rebuilt but I wasn't that ambitious. Had they not moved I would have taken the opportunity to have them revalved for more rebound. I talked to Tommy and he said that when they originally spec'd them it was his impression that they needed more rebound than the shock provided. Apparently there might not have been a consensus (amongst the development team) on this topic but my money is on his opinion.

Thanks for the reply - I am assuming you took them off the car, or did you apply diesel every so often and let the car sit for a week?

John new shocks are on the way I will have them in a few days.
