Can someone please definitively tell me where the two "conical" washers go on the main bolt of the rear suspenson assembly? Do they go on either side of the shock absorber mount or on either side of the wheel hub link? Thanks.

The hub carrier is dished inwards either side ....

That is what i noticed as well, Garth, but I was unsure. Thanks. I will put them on either side of the wheel hub mount. Maybe I'm misreading Tony's procedure but it seems like his description puts the shock between both conical washers. Thanks again!

Hi Bro both of the conical washers go next to the shock, and the flat faces go towards the shock and the bevel faces away, good luck, Stan

OK, guys - this is important!

The spherical washers go on each side of the upright, in the matching recesses, with the round surface facing into the upright on the front and back. These washers keep the upright aligned.

If you get it wrong, the car will be very unstable. When you accelerate, the rear will swing slightly one way, and when you lift off the throttle, the rear will swing the other way.

Ask me how I know...

The conical washers hold the pivot pin centered with the hub assembly's bore. So, the conical washers fit on each side of the hub with the bevel end towards the hub.

The shock fits between the rear conical washer and the large flat washer. Make sure you align the shock end at the correct orientation, so the pivot pin slides on easily. With some extra effort, you can get it installed 180 degrees out, which is incorrect.

Three yea votes to placing the conical washers into the matching hub recesses, one half nay vote .... any reconsideration for unanimity before final submission to Flott?
The hub is allowed a slight degree of off axial articulation by way of these pivot surfaces .... and wally has nicely detailed the consequence of bassackward placement.

Flot..............see my response to your PM. The conical washers go either side of the hub into the recesses. I just completed my Eibach/Bilstien install last weekend so the process is very fresh. The picture Tony has on his site is wrong of which he's now aware and is amending.

Borlands description above is accurate and Garths "off axial articulation" is way too much for this time on a Sunday morning.

Garth, Wally, Borland and Malcolm (and you too, Merlin!),

Thank you all for your responses. After posting I was able to locate an exploded view diagram of the rear hub in the workshop manual (I know I should have looked more thoroughly there first ). The two conical washers go on either side of the wheel hub mount, not on either side of the shock mount. If you look at the hub mount ends you will see the conical recesses that the washers fit nicely into. Trust your instincts . . .

I finished the job last night and took it for a test ride. I will need to let the suspension settle and adjust ride height before giving a final impression but my initial impression is that the ride is no harsher than what I had and the car stays planted and more level in the corners.

Just out of curiousity, how many of you guys have done this job and replaced all the rubber bushings and mounts that lie between the top of the spring and the body of the car? Is that a worthwhile procedure?

Thanks again.

GlenL

I've done that. I replaced every rubber bushing in the rear suspension including the shock tops with the exception of the forward bushings on the lower arm. Didn't notice any improvement. Lots of work, though.

I suggest _not_ doing it unless the bushings are obviously cracked, oil soaked or otherwise damaged.

Flott Leben

Thanks, Glen! That is kind of what I thought (since I didn't do it) but it is nice to hear it confirmed by someone who did it.

GlenL

While the new rubber bits weren't needed, really, there was some benefit I should add.

The PO (or mech.) had re-assembled some pieces wrong and left out some washers. Also I lubed the rubbing surfaces and bolts with synthetic brake grease. It's all correct, tight, adjustable and quiet now.

Ditto what WallyP said, DTDT. In just a few days the aluminum had deep grooves in it.

I am v grateful for the write up on Tony's site, despite the inaccuracy. But he's not alone. Check the pic of the rear shock on Carl's site. Something is not right at all...

Gulp! The shock is on the wrong way. It should be rotated 180 degrees (the weld from the shock to the shock mount should be closer to the rear, not the front). Also, the lower spring retainer plate is missing. It should be sitting on top of the adjuster collar and the spring's bottom should be resting on that plate, not the adjuster. [edit - this is because the springs are hypercoils, not OEM - so, nevermind.]
