Rear Shock Bushes / Washers

NewbieWithA90 · Dec 6, 2023

Hi everyone, I'm reading lots of conflicting advice about the position of the washers on the bottom bushes of the rear shocks on my 90. A lot of pictures on here showing how people have them no longer load either.

I've attached a picture which is how the manual appears to show them - but then some people seem to recommend the washers are flipped over.

They're Monroe's, but didn't come with any instructions and there's nothing on their website about it
Thanks for any help :vb-wave:

Yes that is correct. The gap is filled by the lower shock bracket. If the bracket has some 'cups' spot weled on you can either knock/grind/drill them off and fit as per your picture or remove the two center washers and fit the rubbers into the 'cups' directly.

I would advise knocking the cups off, file off any rough edges, prime/paint the brackets and apply plenty of grease.

Thanks for the reply. That seems to be the way the manual suggests as well but I've seen them the other way round too. I think I will stick with this as you say.

The bracket is just flat, no cups or anything. I've wire brushed it all and put grease all round, so I should be okay to just put these on as pictured now?

As above.

Thanks both. I think a lot of the time it's having the confidence to do it until you ask someone.

There's a lot of discussion on Landyzone about the optimum position of the washers, with some favouring putting the outer ones with the convex sides towards the rubber. I tend to go with the picture provided in the manual or with whatever is in the instructions in the packaging with the shock absorbers. This generally shows concave side towards the rubber. I suppose if you were doing a lot of highly technical off-roading with massive axle movements it might be better with convex sides to the rubber. But then you'd probably put new shocks on several times in the course of a competition season anyway . . .

If on road then use the cups on the axle and one washer above and below as per the pic. Leaving the cups in place and going off road/highflex will lead to shock failure.

If you do any off road remove the axle cups and fit exactly as per the pic you posted.
