I'm tearing into my '94 IM roadster's front balljoint suspension and could use some advise. It has a height adjuster only on the lower beam and the feel and ride is VERY stiff. It has oil shocks. I've played with the ride height a little to make sure the shocks are within their travel limits, of course that doesn't change the spring rate. I'm trying to remove the leaves from the adjustable beam but they are stuck in the adjuster. I've removed the smaller leaves and I'm down to the 4 main ones. A couple of weird things are one of the 4 leaves is thinner is thickness than the others and the grub? bolt in the adjuster has no pointed taper like all the others(rounded, looks stock?) and I see no hole in the leaves (looking into the adjuster slot) for the bolt to key into. I don't know who made the adjuster but seems to me the leaves should to anchored like a stock beam? Anyone know about the different adjusters out there?
I've read on a lot of forums about changing the spring rate so I plan to remove all the small leaves on both beams to leave just the 4 main ones top and bottom to soften the rate. I'm concerned about the one thin leaf not fitting correctly in the adjuster and trailing arm keepers plus I can't get them out anyway at the moment. Why one thin one is a mystery. This leaf does have part of the tapered hole on both sides for the trailing arm grub bolts. The upper beam doesn't have any of these issues.
With all the repairs I've done I probably should have started with a new beam and trailing arms.
Any ideas? Thanks.
