Even when the rest of your suspension seems tight...
...adding the slightest resistance to just one of your front wheels is enough to alter your suspension geometry, 'bringing to light' even the slightest amount of play in the form of a shimmy. I'd never have believed it either had I not been through it myself
All I'm saying is, if you've checked/repl'd everything else, do yourself a favor and check out your calipers to ensure they're releasing. Look for unevenly worn or unevenly "hot" rotors up front, and just make sure both front wheels spin freely. It's a cheap test, and one often overlooked IMHO.

Brake Rotors can cause shimmy
JP,
Bad brake rotors can cause shimmy.
I had a new but not balanced rotor drive me and my tech nuts.
He didn't believe me at first. Got a free replacement.

There is a flex disk and a center support bearing.....
normally it is clever to switch them both together. You probably did.
you can have a perfectly balanced tire, but if its square it will
shimmy until its replaced with a round tire. I have been dealing with this crap since I got my tires at Discount tire scammers, almost a year now. They DO NOT want to honor a defective tire issue because the square tires are within spec. what spec is beyond me. All I know is I replaced everything and it's tight, at a slow crawl the car shakes back and forth side to side, which to me is a bent rim or a good for **** tire, well it aint a rim and the tires within spec so... withoud an AK and a mask I'm blessed with discount tires warranty till I burn the tires to the cords.
Can anyone tell I was there again yesterday wasting 3 hours trying to get this issue taken care of again? Total time must be pushing 15 hours so far...they are nice guys and all, I want to invite them to an ally in detroit and congratilate them on their fine service.
Within spec.
I was readin (dont i always) that tires from Florida are better tires all around cause of the freeway heat and the blems get sent to the other states, anyone hear about this or am I just dreamin about round tires?
I have the aluminum lower control arms....

Think you made the right choice with steel :-)...believe even the most discerning could never tell the difference on the street or track.
HTH,

A previous owner must have installed them.
I didn't even think about it until this thread brought up the subject.
Mine still have the remains of the part number tag/tape on them.
As long as they work properly, I don't mind if they're steel or aluminum. :)
