Rear ARB bushes
Got my rear shocks off today yet again. Rolling Eyes Due to too mount shearing below the collar on the OS shock. (Same one as last time.)
No doubt the red Polybushes have played a part being too hard.
Anywhere they are off.

I'm finding at the moment if I bump the rear suspension up and down obviously it's springy due to no shocks on.
I'm nothing a bit of a 'knock, knock, knock' when I do this.
I'm trying to pinpoint exactly what it is, I'm guessing bushes still and must be either ARB bushes to drag link or A frame.
It seems to be that side and I'm tending to think ARB bushes.
I've taken two photos of the OS which is the side I keep getting a sheared shocker and the NS which appears to be permanently fine.
OSR (the problem side)

Do the drag links needs completely replacing on this or simply the lower bush?
You can obviously see the difference.
Bushes are cheap but the drag link asy and bushes are about £70 each! Shocked

For now I'm going to put an old pair of shocks on and leave but I'm going to sort this ASAP.

Any thoughts?

Also if anyone has any new take off 90 puma rear shocks on the shelf please let me know. Thumbs Up

I forgot to mention, this side is the same side I took a big hit in a pothole some months back. (It was hidden in water.)
I'm wondering if the ARB is putting the shock out of alignment on that one side perhaps due to the bush being knackered and putting stress on the shocker.

Think that is just the end of the protective plastic cover which is on the first couple of coils. Good spot though!

As munch said the ARB does what it says on the tin, lessens body roll. Personally as it is easy to do, I would remove the rear spring for a proper look at it before discounting it as the cause and moving on. JMTW Thumbs Up

Thanks for the replies chaps, sorry I've been delayed coming back it's been internet change over day as well.
So been offline for a while.

That's just a bit of powder coating flaking Brian, I found the source however of the minor knock.
It appears that it's coming from the very top of the spring tapping on another part of the coil that is close.
I'd say it's a sign the springs are getting weak and need changing as they are getting compressed.
They are 7 years old after all.
Reason I mention the ARB on that side is when cornering a weak bush must surely allow some more body roll which will mean more stress on that side.
I've fitted an old pair of rear shocks for now with OE bushes.
I'm going to have to look into getting a pair of new rear shocks, ARB bushes need changing as a matter of course and possibly springs too.
When I first had it. (I wasn't the first owner they did 12k) The springs were yellow, I'm assuming S***part.....
I left them and have done but the powder coating quickly disintegrated and I've keep them rustproofed ever since.

A spring change isn't too much of a job is it at home?
I know the front shocks can be a pig to get off but they shouldn't be bad at all as they've only been on about 8k.

I'm tending to now think that the 'pothole incident' probably put an end to ARB bush that side, probably didn't do the spring much good either and has then of course affected the shocker that side too.

Not so worried about the cost as I'm sure I can get OE parts for good value but the work is plenty.
Least it's safe and drivable for now.

Steve - just noticed a post on 'Angry Pumas' on Facebook from a guy who has had both rear shocks on his 90 split around the top shoulder, which sounds exactly the same as the problem you have had with yours? 2005 Td5 | 90 Station Wagon | Tonga Green

Yep, I've had this twice on one side now.
Do you have any more info?
Remarkable part is the old shocks although old and with OE bushes that are heading toward the end of their life - they seem to keep going.

Are they made of cheese. Whistle

You can change the whole arb short linkage or just bushes. Looks like bolt is out of alignment so check linkage shoulders for wear too.

Springs, they last for ages. How many miles of doing what sort of use have they had.
Seems like unnecessary work changing them.

Shock s are fitted correctly at top I assume, what brand are they that keep snapping? Cheers

Hi JST,
Apologies for the late reply, for some reason I missed your posts.

From when I looked it looks to me like the bush is knackered and putting the bolt out of alignment but you could be right.
When I have it off I will certainly look for any wear on the linkage.

It's too coincidental this has happened on the side the I hit this pothole.

Shocker top mounts are always fitted to workshop manual specs inc torque.
I have been running on Polybushes and I think they are part and partial to the upper collar shearing as they are the red performance versions which are the hardest.
I'm going back to OE rubber for this reason.

This springs I want to change over on age grounds and the fact the are aftermarket anyway not to mention slightly rusty all be it I have kept the Dinitrol protected.
In the process of getting various parts but when I do get a chance to crack on with the job I'll report back hopefully.
