I replaced my standard springs with Eibach itmes on Sunday. It was all good driving home from my mate's house where we'd done the work on Sunday evening.
Noticed yesterday driving home from work that I had an annoying creaking / twanging sound coming from the rear passenger side.
With my hand on the spring as I was jacking the car off the ground, you could feel it sort of 'twanging' as it was being uncompressed.
I stripped out the rear seat, etc again last night and loosened & re-tightened the shock strut top nut - as well as spraying some WD40 up to the underside of the top mount area...but can't really get to it without dropping the entire shock out again.
Everything is tight.
When I took the car out, the twanging/creaking stopped for a few minutes after I'd been jacking the car up and down, compressing and uncompressing the spring whilst I was investigating last night. But came back again.
It seems to creak when the car is level and just travelling down your average, slightly bumpy British road.
It stops creaking if it's compressed (I did a few laps of a roundabout on the way to work this morning) or the weight is taken off the passenger side (ie: by taking a left hand corner...doesn't have to be taken particularly agressively either).
Any thoughts before I spend my Wednesday evening out in the cold & the dark stripping the thing down again?
