Suspension bushings and Bilsteins
Just got my crispy new Bistein /Eibachs on the car and no longer bob down the road. The ride is firm and not harsh, thanks to all who recommended them.
At the same time I replaced the lower control arm bushings with urethane ones. I had seen postings saying they were a bitch to fit, no surprises there!
This is how I made them work. If you compare the large [front] bushings to the shaft they fit on ,the radius on the rounded end is not a match to the one on the control arm. I have access to a lathe and i found by trial and error that if you first cut a slice off the end with a hacksaw, maybe 3/16", then in the lathe open up the radius to match the control arm they slide on all the way and then your bolts will line up.
By time i got to the 2nd side i had figured that the same treatment to the smaller bushing [ without the hacksaw part made it slide fully on to the shaft alot easier.
Also found this cool thing in the design of the suspension, the lower ball joint has a built in feature that when you undo the nut it presses out the stud of the ball joint! Just tap on the side of the upright at bingo it's off no pullers neccesary, cool!
Oh yeah, to figure out how to turn urethane i just typed in" turning urethane in a lathe" in my search engine[ google]
