Hey guys,

Had to wait four weeks for one of the shocks to be rebuilt. I bought them used.

Just picked up my car from iND after my KW suspension was installed.

My question is that when I hit a bump, a high pitch squeaking sound occurs? Anyone ever experience this or know what it could be?

Some shops don't re-use all the OE washers and/or they install them upside down/in the wrong order. This usually doesn't cause any mechanical issues with the suspension, but they are there to prevent friction/binding/squeaking (binding is very bad). Also... there is a paper thin gasket between the strut mount and the shock tower and this is commonly not replaced during aftermarket suspension installs.

Those are not necessarily your problem but they are fairly common suspension install failures that might be worth looking into. I'd start simple though... WD40.

I offer you a preemptive apology for hurting your pride and/or feelings for any comments I make to this fact.
