Hi All

Putting my 85 Euro back together and wondering if someone can confirm orientation of the rear shocks?. Information in WSM and other sources is somewhat ambiguous. The bottom mounting and main tube is offset/slightly angled, do the shocks "lean" backwards or forwards on their lower mounting pins?

They lean forwards backwards from the bottom mounting.

Thanks DrBob, lifesaver..

FWIW, you have to beat the pin into place with the wrong orientation. If the pin doesn't slide in easily, take another look. Another reminder is to coat the pins and stuff the shock bushings with anti-seize, so the pieces don't become one with corrosion over time.

Thanks, the pin is putting up a fight on one side - I will check orientation. I have "slathered" it in antiseize to use a local term, which thankfully someone had done in the past - one of the few parts of the suspension that came apart without a fight..

When you put it back together, make sure you torque the nuts on those pins to correct spec. If the torque is below spec, the rear of the car will yaw noticeably, particularly under acceleration and braking.

Plus the arrangement of the washers is critical to keep the pin (and the shock bushing) centered in the carrier and control-arm sections. Ultimately, all the steel bushings get clamped so they rotate together as one in the rubbers. Ideally that tightening gets done with suspension in final position or close to it. That means supporting the car on the suspension (blocks, jack, stand) for while the wrenches go to work.

ok thanks for the intel

ok I see, that makes perfect sense. I did at least have the washer in the right place though.😊

Tilt to the rear.

I crawled under the car and took a picture to confirm my response. Still got it wrong...

Editing my initial response. Sorry!

Haha, thanks Rob & Bob. That diagram was one of the ambiguous ones given the perspective. At one point last weekend I concluded tilt to rear but then was not sure as it's very subtle. I too crawled under my GT but not full ways and still difficult to tell. REAR is is

Yes I checked both my 928s and the tilt is to the rear, this is to line and orient the shock with the opening in the chassis. The way I look at it, the base of the shock where the loop is welded to the cylindrical shock body has a "fat" opening and "skinny" opening, the "fat" opening is to the rear, the "skinny" is to the front of the car. Happy to provide a picture if need be.

Thanks slowandrusty, I think I've got it right, will post pictures when I have assembled the whole suspension as there might be other assembly errors. Currently wresting with driveshafts, why is everything so difficult?...

Not sure that tilted 'front' or 'rear' is a good way to phrase it.

I prefer the idea that a long pin through the shock would have the rear sitting higher than the front.

The pic from the WSM is a bit subtle, but you can see that the upper left & lower right are smaller angles than the upper right & lower left.

Placing something with a proper right angle (corner of a piece of paper does the trick) will show this quite clearly.
