[s-cars] Good news - bad noose

[Mark Strangways]

Could also be the bilstein strut nut allowing just a bit of slop at the top 
of the strut.

BTDT... hence the washer fix...

>> Hi Y'all,
>>
>> Suspecting a blown RF strut cartridge I pulled mine (Bilstein HD).  I

>> The good news - the cartridge and the strut bearing both appear to be OK.

>> The problem: a severe shimmy in the RF wheel/tire (it feels almost to be

>> 3.      subframe bushings
>> 4.      lower control arm bushing
