Top mount nut torque settings

I want to change my top mounts this weekend.

Can anyone tell me what the top mount nut torque settings should be please?

Hi

Both nuts,.70 & 71 are torqued to 65Nm (48 lbf ft)

Thank you!

Ensure that the washer (item 3) fits correctly into the bottom of the adapter (item 8) as the spring is un-tensioned. The top of the adapter must sit perpendicular to the shock shaft. The force of the spring tends to cause the adapter to sit on a wonky angle if the washer is not settled into the recess in the bottom of the adapter correctly. If possible, compress the spring so that there is no force on the washer, mount and nut (items 3,5 and 71) when they are done up. Carefully guide all the free components as the spring compressor is relaxed.
This is definitely a 2 person job or the adapter will sit crooked every time.
But if you did it last weekend...then you know.

This is great advice thank you! I wish I'd seen it before hand though as the jobs done now. I actually had a mechanic change the top mounts and shocks before. Both new top mounts failed some how. He put it down to cheap parts but I don't know? Here's what top mount from the side I did looked like:
And here's a video of the issue...

It looks like he hadn't lined up the top mount properly, where the pin hole is... not sure if that matters. Also, the spring wasn't seated in the base of the shock properly. There was a gap of about 2 - 3cm, which I think was the cause of the clunking?

Any way, it's a really crap job and I did end up losing a bit of gearbox oil. I didn't end up taking the hub bolt off, which might have made it easier but it was super difficult getting the shock back into the knuckle! I had a friend help thank god, there's no way I would've been able to do it all by myself. I threw the original top mounts on and used the new bearing from the new kit as they were all fine.

Noise has completely gone away now and it feels great.

IMHO these are a stupid idea! There is no way that the rubber will NOT eventually strip off the the metal bush!!!!! There are both longitudinal and radial forces on the rubber to bushing join. The action of the shock absorber is not "frictionless". How can it not eventually separate?
PSA continue to use these stupid things across their Citroen and Peugeot range! Then guess what? They make the top mounts and bearings just slightly different. WHY!!?? They could make them all the same, the difference is @#$& all! There is no need for the very small difference between them.
Sorry, rant over.

The design is super crap honestly and I feel like swearing a bunch too! The side I swapped out is now knocking again... exactly the same issue before.



Do you have any idea what could cause this? Last I checked, the sprint wasn't seated against the bottom metal tap, there was a gap of about 3cm.

Sounds like the spring is moving and hitting against it every time the steering wheel is turned.

Apologies I don't know if there's relevant access to the video but here it is - https://www.veed.io/view/197ddde7-6d59- ... anel=share

Wow! It sounds like a base drum!
I assume you were just moving the steering left and right?
The retainer disc is sitting up a long way. I don't think the strut is assembled correctly. The raised "lip" thing on the top pad should be on the outside (outer, close to the fender).
I know its a different model to yours but here is where mine is sitting. Also, the shock shaft is moving around a lot. Does the shaft on the other side move around too?
The booming sound could be something sticking and then releasing, like rubber on rubber. Is the upper bearing OK?

Figured it out! My dodgy local mechanic really messed up both sides... not aligning and tightening things up properly.

The issue was on the drivers side... Nut 71 was massively under tightened so everything was lose. I tightened that down properly, realigned the top mount as the pin holes didn't match up, and I had to reseat the spring against the metal tab on the base of the strut.

After all of that there's no noises again!
