Suspension Bushings and Control Arms Master Thread
Hello everyone. I've been reading thread after thread to determine what works and what doesn't I was thinking it would be great to have one place we could find all the parts needed to overhaul the front and rear suspension.
(I'll make edits as we fill it in to make it easily readable.)
What I think I know:
Front Upper control arms: easily sourced from rockauto.com LEMFÖRDER is the most popular option on this forum although the other brands should fit just the same.
LEMFÖRDER 3063101 Alternate/OEM Part Number(s): XR81764, XR852091, XR856013}
Front Left Upper; incl. Ball Joint and Bushings
LEMFÖRDER 3063201 Alternate/OEM Part Number(s): 4W4Z3084AA, 6W4Z3084AA, XR81763, XR852090, XR856012
Front Right Upper; incl. Ball Joint and Bushings
FORD THUNDERBIRD 2002-2005
JAGUAR S-TYPE 2000-2002
LINCOLN LS 2000-2006
Would the lower ball joints and end links be interchangeable? I used Lincoln LS outer tie rod ends on my 2003 S-TypeR
1 x Part # CF6W4Z.3085AA 521-429 Front Left Upper Control Arm
1 x Part # CF6W4Z.3084AA Front Right Upper Control Arm
2 x Part # K500084 Lower Ball Joint - 14MM
1 x Part # ES800414 Outer Tie Rod Left
1 x Part # ES800415 Outer Tie Rod Right
2 x Part # K80261 Front Sway Bar Links
Look at 2003 -2008 Ford Thunderbird and Lincoln LS. The price is half or less. All the upper arms and rear lower control arms are the same. The rear toe adjusters are the same too.
The front lower are different. I think the front tie rods ends are different also.
I might have gone with Moog arms knowing what I saw. Looking at the pictures on eBay the Moog arms look identical to Lemforder. The other brands do not.
Except for the air suspension system, LEMFÖRDER (Lemfoerder in English) is the Original Equipment Manufacturer (OEM) of most or all of the suspension components on the Jaguar X350. Rock Auto carries a lot of Lemfoerder parts, though some of them are only listed in the sections for the S-Type or only for the Lincoln LS or Ford Thunderbird, perhaps because for some strange reason the Lemfoerder catalog doesn't mention that they also fit the Jaguar X350, even though they do.
You can look up Lemfoerder part numbers in these catalogs:
Found a picture that really helps to show the bushings for the Front - Rear Lower Arm. The EPC has it wrong in matching up the part number with the diagram on this one.
Largest end bushing is C2C4437 = ZF Lemforder 29784-01 @ approx. $20 part
Smaller near other end bushing (middle) is C2C18350 superseded now to be C2C36866 = ZF Lemforder 35353-01 = Beck Arnley 1017517 @ approx. $25 part
Smallest very end bushing is C2C4438 = ZF Lemforder 29785-01 = TRW JBU638 @ $15 part
Just note that the part prices actually range quite widely sticking to OEM parts depending on who you look up on the web.
I hope this helps because I was thrown for quite a while by the EPC until I did searches on various UK British Jaguar sites.
Free shipping available. Leave it in your cart for one day and you'll get a 5% off coupon the next day off $199+. Add a random screw (if still the same cost as the time you're reading this) and it'll come out to $189 for OEM front uppers.
Hi dsetter,
I may have used your posts in my putting together of this one so thank-you for doing the research for me.
I have a mixed message ONLY on this part.
The front Lower Curved Control Arm.
The smaller bush, on the outer side is NON-REPLACEABLE. NON-SOURCEABLE.
When in engineering one comes upon this then you have one choice but you can make it into two choices if money is really tight but I do not recommend it.
The entire arm has to be replaced so-as you replace the smaller bush.
The smaller bush is not to be removed once fitted in-place. Because of the small surface area of the alloy encasing it, any stress or bearing press can or will cause fractures or hair-line cracks so the maker will NOT supply this part separately on safety grounds. If you look at the front rear lower arm, this has three bushes which can all be replaced, the smallest bush has a lot of surrounding alloy to take the stress. As I write this no doubt some Chinese company are already trying to replicate it and supply a bush.
I said a second choice, this is one I will NOT do but I know people are sometimes hard-up for money so here is a way out but NOT recommended by me.
You use the same arm and only replace the bigger inner bush on the understanding the smaller bush is NOT a load bearing bush like the others, therefore it will outlast the others.
You can then do the bigger inner bush, thus you have used the smaller bush twice.
Third time you have to replace bushes then you have no option but to replace the arm itself with new bushes.
I have read and researched a lot on this cars suspension geometry, nothing new I came across and Jaguar have done not a bad job on designing it. The geometry and type have been around for many years now.
Separate and independent suspension at all four wheels, means excellent road handling with all 4 wheels keeping in constant contact with the road.
The lay-out is actually designed for racing cars and cars of high end specifications. Yes like other makers also.
Years ago I used to race for an Irish racing team in Scotland in Formula ford 1600's and Vauxhall 2.L's.
I used to get up to 170mph (my latest motorbike does more than this!!)and when you are cornering with 10 others touching your tyres then you will understand how crucial the entire suspension geometry becomes and how one single faulty bush or bearing will wreck your race and normally your car. The parts are normally titanium etc., but all the same principles of how it all works.
This is why I will be hard on anyone trying to save money on parts.
When cornering, if any movement or flex in tie-rods or linkages then you are off the track, no matter how good a driver.
This brought me over the years to a few colleges and universities with Brunel being my last one as this is when my accident happened.
Please, can anyone tell me what the torque settings are for an "05 s type front lower control arm. It's the large curved one with 1 large and 1 small bushings. I've tried everywhere with no success. Thank You.

My 2006 VDP has 101,000 miles. Upper control arms (both sides) were replaced at 76,000 miles. Front lower curved arms were replaced at 40,000 (LH) and 66,000 (RH). When doing my oil change yesterday I took pics of the bushes. To me they look OK, no obvious tearing or breaking, but of course a visual inspection is pretty superficial. The car still rides very well, but I did have a vibration through the steering wheel when braking, which seems to have been cured by rotating the tires. I suspect I will have to take the plunge and replace the bushes in the rear lower arms and the anti-roll bar bushes and links too as those are original to the car. Any thoughts?

The rubber items shown look great. The rear bushings may need replacement. The inner bushing on the LCA seems to fail.
Everyone I know, both online & off, that has ever bought Deutsche Parts has STRONGLY recommended that I NEVER EVER buy parts from them. Try Googleing the name & see what pops up, or better yet do a forum search. As always YMMV
I redid my rear bushings with Deutsche Parts. Two bushings were the wrong size. They corrected very quickly and no problems at all for 6k miles and they still look good and feel good.
Upper control arms can be bought online as Ford/Motorcraft parts, but will come stamped "Jaguar" and "Made in England"
Hear are the part number equivalents, posted by Jahummer a while back:
FRONT
MotorCraft MCSOE38 = 6W4Z3084AA
MotorCraft MCSOE39 = 6W4Z3085AA
REAR
6W4Z5500AB
6W4Z5500AA
I can confirm that the front control arms are correct and that they had "Made in England" and Jaguar indicated on the parts when they arrived. You should be able to find the OEM upper control arms with the numbers above for about $130-140 per side.
