I have an 06 x350 I am getting back on the road. Just did rear wheel bearings and Rack and Pinon Steering. While doing so we discovered that it needs rear tie rods and the lower bushing on the lower control arm. I have found a few threads here talking about the Upper control arm and several on the front arms BUT very little on the Lower rear control Arms.
I have found a bushing for $50
But I also checked Barretts and it doesn't look like there was an actual part number for the bushings - Did Jag intend people to replace the whole arm ? I found a jag manual that has 4 specialty tools to remove and install new bushings - are they really that precise ?
Would it be better to just buy the whole arm instead of trying to remove and install a $50 bushing ?
There is a thread that says the upper arms can be Ford (Lincoln LS) control arms from Ford for around $160. "Genuine Motorcraft" with "Jaguar" cast into the metal
Part numbers 6W4Z5500AB

Does anyone know if there is a ford part number for the LOWER Arm ? are any of these the same as the S-Type ?

I have found a no name lower control arm with all 3 bushings on ebay for $125 (Mainline automotive)---- anyone ever install these no name ebay parts ??? My instinct is to stay away from probably Chinese knock offs - but the only options that come up on parts searches with the jag numbers are the no names and Brit Parts for $300

Also Barretts suggest there are different part numbers for the lower control arm depending on VIN - but all the aftermarket descriptions just say Jag xj 04-09

Thanks for any help

 

The rear lower wishbones (as we call them in the UK), are an 'old chestnut' with X350/358 owners ! Known to start wearing at 30-35 miles you can understand the angst of owners when each side was costing nearly £500 to replace using "Jaguar" parts. It was discovered fairly early on that the part was identical to the arm used on a Lincoln. Logical when one knows Jaguar were owned by Ford at the time. These arms were half the price of the Jaguar official part, and were soon being installed by DIYers and independent shops.

There is a safety element in replacing the worn bushes onto the existing arm in that the arm is an aluminim casting and if not done right can cause cracking of the casting. My local Jaguar independent at the time I owned an X350 and also, later, an X351 (lovely cars !!!), set themselves up to replace these bushes with press and mandrels but suffered some cracking so gave it up, as it was too much risk for the company. Also, by using the Lincoln wishbone, the cost of their labour to replace the bushing meant the cost of a new arm was not hugely more than replacing the bush.

Here is the SNG Barratt entry for LH and RH rear lower wishbones. The Lemforder ones are the ones that I would buy, but obviously for a car that is not a daily driver the cheaper arms are worth considering

Also here is the Berkshore Jaguar Components listing for the same parts, (UK supplier in Berkshire !!).

I believe they ship worldwide too.

 

Thanks for the reply Fraser, I was originally thinking a rubber bushing wouldn't be that bad to press in, but after seeing all the special alignment tools I am more suspicious of my general mechanic doing this. I would try it if the bushing was reasonable price but I am seeing them from $50-$80.
Thinking of going entire arm, but need something I can get delivered in a few days.
Does anyone know the Ford part# for the later 2006 VINs for those lower rear control arms ?

 

USA based (at least until NY secedes?).....

Try for a Moog listing. Popular supplier to many distributors.

Per prior posts to this site, Moog buy the OEM Lemforder, grind the maker's info off, re-mark with Moog SKU.

 

FWIW, in 2022 I replaced both the lower control arms on my 2004 XJR with Dorman 521-937 and 521-938 (left and right). It was a perfect fit and continue to work great.

 

Dorman is a major old-line supplier with really, really BROAD sourcing. Most of my use of their parts has been on Chrysler & GMC vehicles.

"Globalization" as it is - or WAS - where an X350 Jaguar has parts commonality, 'at all' ......it is mostly with Ford on mechanicals, Japanese or German sources on transmission, fuel system, electricals, and air-con.

 

bushing is available from lemforder but not worth the time and effort.

the lower arms and knuckle changed in 05 they have a narrower bushings. anything xf xk f-type x351 etc work for those

 

I noticed that the SNG Barratt link you shared has the rear lower wishbones for the S Type and XK. Does this mean that these rear lower components are the same across the XJ, S Type, and XK?

 

Seasonal greetings!
I decided to treat Big Koshka for set of new rear CA both upper and lower.
It seems to me a strait job, as strait it can be on suspension that 21 years old!
If someone will be willing to share their experience on doing same job or pointing me to a thread I most likely missed, I will be greatfull!

• I am perusing various threads on the subject. I also have downloaded shop manual. One thing I can't find is section with procedure to disconnect height sensors. May be I am missing something?
• I know I need to make sure parking break is not engaged to be able to remove caliper; is there a need to disconnect e-break link from caliper as well?
• I am planning to leave car for hour or so with trunk lid open and than sneak on on a car and disconnect battery. after that I will lift it up.
• There is a QuickJack in the garage; so I can get get all 4 wheels up in an air. Manual says lower car on ground and tighten suspension bolts. How would one accomplish that in DIY environment? Support lower arm with jack at approximately correct position, one side at a time?

My thanks gow to everyone willing to share their experience.

The sensors use a metal clip, designed to be reused..
Just take your time you'll see, hope yours are not too rusty for reuse.
Don't really see an alternative way to adjust the suspension height.
Have yet to see why the brake line needs to be routed through the lower arm though.

Basicallly, that's what I do, but I do not support the respective lower arm with a jack. I put on the wheel and drop it onto part of an old tree trunk (app.1 meter high, that gives enough room for working with a torque wrench).
