As far as the self leveling part, I will measure to see if the rear height is correct (19") per Max' advice. Otherwise, the car never sags during periods of rest/disuse. On Mon, Jul 12, 2010 at 12:15 PM, Fmiser wrote: > > andrew strasfogel wrote: > > > I've since replaced that used one with a n

I've since replaced that used one with a new one, so the car now has two "fresh" accumulators. And yes, despite the wawrnings I received a dousing of used SLS fluid when I disconnected the line into the sphere. It's not that bad, BTW - sort of like a cocktail of 10W30 and biodiesel. On Mon, Jul 1

I would proceed in the following order: 1. Check the rubber mounts at the top of the strut. If you had bad spheres, these mounts may well be pulverised/absent. Check also the bottom balljoint. 2. Test the function of the levelling valve (see instructions below) 3. Remove and test/replace the st

I did a road test and the car seems to handle the bumps fine when I maneuver so as to hit potholes on the left (good) side. I think it's worth a try to R/R the right rear strut that's leaking. As for the spheres - they're both NEW and operate as they should. On Sun, Jul 11, 2010 at 11:15 AM, Kal

as for the speedo, it seems we just went over this recently, but i don't recall the outcome. have you verified you have the correct speedo in there that was matched to the higher rear-end ratio of the '85s? (you should be able to read the P/N at the bottom of the face of the instrument panel.)

I told you months ago the speedo parts in the tranny were the same. As for the SLS, the strut has nothing to do with acting like a shock, its the job of the spheres. I dont think a slightly leaking strut could cause the problem but I could be wrong. Maybe you got some bad spheres. If the ca

The spheres ARE the spring (the part that allows movement and produces "spring" effect). The damping is provided by the valving in the struts, and the height control is provided by the volume of fluid in the bottom half of the strut vs the upper half, controlled by the valve on the sway ba

He said that the function of the struts was to act as a shock absorber, yet I thought that was the job of the air cells. Consider what the nature of 'shock absorbtion' is. The sudden onslaught of kinetic energy is taken up in a spring, and released more slowly, dissipating the excess as heat.
