Have diligently searched to no avail. Preparing to Install KONI Yellows and Swift Springs. KONI instructions for rears are impossible to understand. Have a package of steel tubes, washers, nuts and plastic collars. Have learned from previous posts that you have to drill out a washer so it will go over the strut shaft. Can someone explain clearly the correct assembly procedure? TIA!

 

The round white plastic washers go on the strut, before anything else. The steel tubes should be wide enough to fit over the top of the threaded portion of the strut. You'll notice the stock metal tube does not fit. What you need to drill out is is 2 things, the actual metal upper strut mount, that hole needs to be expanded so the shock shaft can to through it, and then the metal washer that goes under the nut that secures the entire thing at the top. I forget the exact size that those two pieces have to be drilled to.

Part Numbers 12 and 9 need to be drilled out.

 

Thanks, blue2turbo! I hate going into a project blindly. If I do, it usually means I get to do it over at least once more.

 

Project FTW!

 

Upon disassembly of the rear shock assembly, I found a hard durometer black polyurethane inverted bump stop on the bottom of the shaft of the old OEM sport shock. Did you find one, blue2turbo? If so, did you install it?

 

No I did not have those. If you ran into a black poly one, sounds like someone must have swapped them at some point for the HSport bump stops.

Should look like this?

If you have those and not the factory ones, you can just reuse them, but you definitely want to have a bump stop of some nature. If you have the factory ones, you'll want to trim some from the factory ones, preferably from the firmer part of the bump stops.

 

Duh! It was me! I found my old instruction brochure from the H-s
Sport Springs and, sure enough, it supplied the special bump-stops and I installed them...Just getting senile, I guess. Thanks for reminding me.
