My 2006 S Type's front lower front control arm inner bushings failed. I have found replacements for those (part #c2c39683B if anyone is looking), but can't locate the part number for the outer bushings on the same control arm. Anyone else know what the part number is?
Not in UK forum's Definitive Wishbone Bush thread?
No, I didn't see it - just reviewed the thread this am - good read for sure! Just curious as I need to replace mine pretty soon and I don't want to spring $$$ for the upper wishbone assembly...

The ball joint is part of the upper suspension arm and is not supplied as a service part. Chances are the inner bushes are worn as well, so you will need to replace the arm. You may be able to find a seller on eBay that can supply the upper suspension arms at a discounted price.

Thanks NBCat - that's what I thought.... off to Ebay land...
Remember to 'pre-load' the suspension prior to tightening any bolts on the arms/bushes you replace otherwise they will be prone to premature failure due to the twisting stress caused by the suspension when the vehicle is back on the pavement.
I've been through the UK Forum's Defiitive Wishbone Bush Thread twice and can't find any reference to the outer bushings for the front lower front control arm on 2006 S Types. Found just about every other bushing on the car, but not the one I need.

I have a fluid drip out of the passenger side lower track control arm front. Was it you who had these available rebuilt for $150? STR 2005
I am in Spring TX, ans that would be very convenient
I suppose this is as good a place as any to post some information about S-type and STR lower rear control arms.
I have a set of STR lower rear control arms as well as one spare 2000 S-type 4.0 After pressing out the bushings and cleaning up the STR set, I took a very methodical look at the SC version and the other 2000 S-type. Casting wise, they appear to be IDENTICAL! Bushing Diameters = Same. Casting wall thicknesses = Same. Unless they casted the SC version out of a different alloy, I can't see any notable physical differences.
The only difference I found is that the STR has a different large inner bushing. It was a molded polymer with an Alum. inner core and a thin outer Alum. sleeve that was pressed into the Control arm, versus the fluid filled sealed type of bushing.
I suppose that a different bushing would be enough to get the SC stamp on the control arm casting.
Regarding new bushings, I've decided to go with PolyBush Urathane bushings.
They most likely will end up being very stiff, but I am not too worried about ride quality in my application.
I am also shocked at the price everyone is asking for replacement bushing, no matter what they are mad out of!
The other option I might have gone with are the Silentblocks mentioned earlier in this thread.
So I am trying to fix up my rear suspension on my ‘06 STR. The upper and lower ball joints boots are destroyed, and one of the mounting bushings.
I bought new top arms since the upper rear ball joint isnt replaceable. I hope the bushings are the same.
For the rear lower control arms I was looking for bushings. What is the part number for the lower arms ball joint bushing to the spindle? Is this the same bushing used in the rear arm?
I was going to order 4 Lemförder 37704 01 since that is that the right part? is what I got after researching. Both ends were toast Toast! Rear lower outer ball joint bushing where it connects to spindle Rear upper ball joint
Many listings on E-bay these days for the bushings.
Exactly what i bought for my 06 str..,.just waiting for cooler weather.....look and feel very well made...will push and reinstall bushings with a hardened thread puller pusher with adapters while arm is held in the vise.....tool worked great for the rear shock bushings already

Thats the problem. I am not sure what I am looking for. Ive done about 10 hours researching this and I dont get a clear picture.
I went to the lemforder bushing site at webcat-services.zf.com and put in my car details and it seems to say I need the lemforder 37704 01 bushing there. Not sure if thats a hydrabushing or not but the link you posted says “DOES NOT FIT THE S-TYPE R SUPERCHARGED MODEL”
so I was leaning towards the lemsforder 37704 01 bushings.
But then I found britishparts.co.uk and saw they have a full set of polyurethane bushings and im leaning towards those.
Anyone use polyurethane on an S type R? How do they ride? This seems to suggest there are two different bushings for the rear lower arm for the balljoint (spindle) end and the rear attaching arm bushing Urethane This ad on ebay has the same lemforder bushings (same 37704 01) for the balljoint (spindle) end and the rear attaching point
I wanted to give a warning that I do not believe that the polyurethane bushings are stiff enough to use on S-type suspension. I had a very bad experience using them, under power I couldn't keep my car on the road. The rear end bounced all over the place because of the flex in the bushings. (I posted a thread years ago about this bad experience.)
If you take a close look at the design of the stock bushings, they are in fact more like a ball joint where there is lubricated metal-on-metal contact. One can't get much stiffer than this.
Before the replacement bushings became readily available, I put together my own control arms using spherical racing bushings. Unfortunately the retaining ring for the outer smaller joint kept popping out due to lateral loads. I was never able to get them to stay in, so I shelved the project.
So coming back to this thread, there is a photo running around showing the outer lower rear axle ball joint to be the same as the inner rear lower rear axle bushing IS WRONG. And another showing the outer buall joint is C2D4013. But that number is wrong too. The correct lower outer ball joint for rear axle is the lemforder 3770401 bushing that is 1.85" (47 mm) in diameter.
