Monroe shocks and top mounts

Just fitting monroe rear top mounts and shocks. Easy enough but I have a large, m12 spacer type washer in with the new shocks. Been reading in to this as there's no fitting instructions or explanation included and I'm getting mixed messages of use/don't use, use instead of the original lower curved washer, use in between the lower curved washer and new top mount to create a flatter surface.

Anyone any idea, or better still fitted these?

I simply used the existing mounting parts swapped over from the old shocks.
Look at the bottom mounting eye. From memory it doesn’t have the metal plate on one side of the bush like OE does. The washer is supposed to fit there instead.
 
Wot he said. I fitted Monroe rear shocks a year or two ago and have forgotten all about it but EZ's post brings back a memory of the washer going on the bottom mount.

Turns out they go in between the original bolt head and the metal sleeve to even out compression across the inner sleeve to the hub. Makes sense as the bolt head is only just larger than the same sleeve.

Fitted this morning as it was the final part after replacing the top mounts, bump stops, dust covers and shocks.

All Monroe so let's see how it drives.

Did you end up using longer m12 bolts? The original ones only just pass thru the trailing arm sorting hardly any thread.

Nope. Didn’t see any difference from original as that had the built in spacer anyway.
In my RAF days we worked on 1.5 protruding threads being in safety.

Well this job is driving me crazy! Everything is fitted, torqued to spec, checked, re-checked and checked again. I'm getting the slightest of clunks at low speed but only over slightly rough ground. Can't replicate the noise by bouncing the car or even having it up and grabbing the wheel to jerk it up and down.

I've read the monroe top mounts can be sensitive and I've also read the monroe struts can have a 'fluid lag', both of which would explain this.

Any ideas, anybody......🫣
 
Is this any use? Someone else recently had similar

Thread 'Rear suspension knock - SOLVED'

Hi guys,

After refurbing all the rear suspension on my E86, including dropping the subframe and replacing all suspension and subframe bushes, I was annoyed to find a knocking noise.

The dampers are new Bilstein B4's and I'm running new SE springs.

General consensus pointed towards the damper top mounts. Originally new Febi bilstein, I swapped to the recommended Lemforder. Still knocking.

I bought some polyurethane mounts (Bevinsee) and tried them. Still knocking and louder due to the firmer mounts.

It's definitely to do with the damper unit as a short, bouncy drive round the block...

Cheers, I've read that and it helps, but also doesn't give any real answers. I also read that Monroe top mounts are prone to knocking. I only found this out after fitting them, obviously.

For the cost and time it takes I might just buy a pair of Lemforder ones and fit them. Or a push bike and have done with it!

The annoying bit is I'm even questioning if I've imagined half the 'clunks' as when I get my partner to sit in with me she's not even taking it serious and says it's no different to before I changed everything over.

"It's an old car and they make funny noises" How helpful is that! 😂😂😂
