C5 X7 Front Lower Suspension Arm/ Track Control Arms

Post by carlsberg101 »

Good Evening, I am in need of your expert advice once again.
I've had an annoying "clonk" from the front suspension when braking sharply at slow speed and when I bump up the small step in the dropped kerb when reversing on to my drive. Having spent many fruitless hours pulling and prodding the front suspension I failed to find any movement. I took it in to the garage today and they have confirmed it is the front lower arms on both sides. Which seems to concur with some old threads on here.
I have again spent a long time this afternoon with crowbars etc. trying to replicate the movement but I just cannot seem to do it with the car jacked up on the drive. But I have resigned myself to replace the Lower Arms/ Track Control Arms anyway as I've got lots of enforced free time at the moment.
Any hints or tips that might make this slightly less harrowing? I'm looking at the EuroCarParts replacements (Product Code: 615735429 & 615735439) although I'm rather dubious of their quality so any alternative suppliers would be appreciated. GSF are considerably more expensive as usual but I did stumble across a new company to me, AutoDoc which seems cheap and they do lots of instruction videos, the only trouble is their parts numbers are a bit confusing.
Ref parts numbers VIN for my car is VF7**************[VIN obfuscated, can be read by forum staff] if anyone has the time to look up the correct part numbers.
Ta very much. :-D

Personally I only ever use genuine parts or Lemforder.
I spent too many years working in garages and fast fit type places where we always fitted the cheapest and then did them again under warranty for the next MOT.
Never had such issues with Lemforder so that's my preference if the genuine bits are too ridiculously expensive.

See my post here:

It was impossible to replicate without getting the car off the ground and using 'The Swede' with a crowbar to move it.

It clunks on braking and stopping occasionally - depending on speed / force / etc. I've arrowed in yellow where the movement was on mine that caused the clunking and the bush that needed replacing. These can be bought separately (not from Citroen) and replaced without changing the wishbone.

Thanks for the excellent advice as always.
I tried again this morning and if I lower the car to take some of the tension off the lower arm I can just about see the slight movement in the Pivot Arm Lower Suspension Bush.
So I'm off to GSF to collect a couple of bushes for just over £30 as opposed to £591 garage quoted for 2 new lower arms.
Fingers crossed this works and wish me luck with a "DIY threaded bar and large socket" tool to extract the old bush and insert the new one. :)

£30! - Yes, that sounds like extortionate GSF prices. I think I paid about £10 for the bush - they are widely available on line and my mechanics ordered them directly and fitted.

Some Heavy Duty ones here cheaper £24.99 free delivery for the pair.

I did mine for the MOT in January. I had the same annoying knock for ages and couldn't find until the MOT test.

Very easy job to do a threaded rod, 2 nuts, 2 large metal washers and 2 large sockets to fit the either side and draw the bush out. I think the rod is M14.

Refit is opposite to removal remember which way they were fitted.

I can't see where in the advert it says heavy duty. Are you sure?

Blurryell, you'd think they'd mention it down in the description which is where I always go to find out details of the product in question.

Maybe these Carlos Fandango super Jam Jar bins would help?

Just for reference I recently got 2 complete Delphi lower arms off mister-auto on ebay for less than £60 each delivered.

Final Update:
I ended up replacing the Pivot Arm bottom bushes and both Lower Arms. Not overly complicated just fiddly and rather time consuming. All parts from GSF as I just wanted to collect them and crack on with it rather than waiting for delivery. Lower Bushes £31.96 for the pair and the Lower Arms were £170.04 for the pair after the usual discounts.

Removing and installing the pivot arm bushes took some trial and error. The socket and threaded bar just didn't work as the bottom of the pivot arm is flared so the socket wouldn't sit square over the bush. If you look at the special Sealey tool the cup that sits over the bush has a cut out so it sits square. I ended up cutting a short length of scaffold pole then cutting it lengthwise to open it out to fit over the bush. It wasn't pretty but it worked rather well, although I had to beef up the threaded bar to I think 12mm as the thinner bar just kept stripping its thread when I tightened it really hard. By the time I got to the other side it was quite efficient. The bushes still needed a fair degree of persuasion with a big hammer in addition to the pulling force of the threaded bar. The video for the Sealey tool makes it look so easy, for the sake of £80 I would be tempted to splash out on one if I ever had to do this again (that's assuming it actually works).

Once I had removed the lower arms I was surprised how bad the rear bushes were on both sides even though I could not see any movement when it was on the car. Removal and replacement was quite simple. The hardest part is getting everything to line up so you could get the bolts back in. It took a lot of faffing about with jacks and levers but it would have been a lot easier with an assistant.

Hopefully it will be a little while before I'm forced to get underneath this car again. (fingers crossed) :roll:

good work Carlsberg!
I was doing the upper arm bushes recently, and my 10mm bar was stripping to! and I couldn't easily get a socket to fit quite flat.. I must buy some proper tools for pressing etc.. mandrels or whatever they are called..
