Top mounts
Hi folks, I've asked a few questions on rear suspension and thanks to you my understanding has grown. one more !
my rear top mounts have paint markings on them and I've tried to use a "keep things the same" approach. However I like to understand better. On jackals forge for example I see this pic :
How do you know you have your top mounts the right way oriented? For example does it matter if the paint mark is towards rear or front if all the nuts are securely on.
sorry if that's a daft question - to me it sits flush at the rear both ways round but I do notice markings on mine too. How do you know if it's right?
Thanks!

I actually just stumbled across this last night while doing the same job.
For the front, the paint mark should be pointed forwards. For the rears, follow the information below, which explains the actual orientation of the shock mount. The four top nuts get torqued to ~25ft-lbs.

I ordered new mounts and don't recall seeing any R or L markings on the top. Looking at pictures in the PSS10 install thread I don't see the pictures either: https://rennlist.com/forums/993-foru...l#post13817654
Visually, the top mounts look symmetrical left to right.
So my question is: I wonder if this is still a relevant instruction when installing PSS10? If so, I'll need to pull mine and double check the orientation.
Is there a similar orientation requirement for the front? I don't think the fronts can go in wrong, they are assymetrical and only fit one way, so I believe those should be fine.

Looking at the shop manual and comparing it to the PSS10 diagrams I think I see why this is necessary in the original shock. In the stock shock there are asymmetrical parts below the mount that need to be oriented correctly.
In the PSS10 these parts are not used and all is symmetrical. So I don't think the orientation matters with a PSS10 install.
Not sure if OP is installing PSS10 shocks but this thread caught my attention given the fact that I just installed mine.

Ah, sorry about the front vs. rear mixup. Paint mark has to point forward up front, as that mount isn't symmetrical.
In the rear, my new shock mounts do have the L and R marking, and I interpreted the instructions on their orientation as a way to get the shock mount to align properly when installing the shock into the car, but in practice this morning it's not really that helpful. They tell you to align the L/R marking with the "ball joint bolt" which I don't know how'd you do with the shock out of the car.

I'm still stuck on whether it matters when doing a PSS10 installation. Since you have yours in-hand, do you see any assymetry in the mounts or the stops (those boat shaped things on the top)?
I don't see mount orientation mentioned in the various PSS10 instructions and tutorials I've found.

IIRC, the rubber and upper washers (aka stop plates) are assymetrical. Their orientation vs the mount is determined via the 3 notches in the center opening. The PSS10 instructions assume you return them to the original positions.

The paint mark should be pointed towards the front, but that's really just a visual cue for the information below, which explains the actual orientation of the shock mount. The four top nuts get torqued to ~25ft-lbs.

Curious, I went back to my photos and found a shot where you can see the "R" (in yellow), and the notch (in red) that should point to the center of the drop link ball joint. Based on that, you should be able to confirm 100% that the top mount is oriented correctly.

Good find. Do you think this is observable while the shock is mounted in the car or does it need to be dropped?
