I have been looking into gathering the bits and bushings to renew the suspension of my '15 XF AWD and have noticed that up front the "rear lower control arm" differs on the AWD car vs the RWD cars in that it is forged with five holes through the web and generally is a bit more lightly formed than the equivalent part for a RWD drive car.

It's easy to get fairly complete sets of all this stuff on eBay, either the components with bushings already in place or just sets of the bushings alone. My question is : Have any of you folks used this aftermarket stuff and if so, has it worked out well for you? I can get the front end stuff for my XF but it comes with the hefty non-holey rear lower arm, not the nifty one with the holes. Back of the car all the same .

I can't imagine there's much difference in the geometry of the parts and I am left wondering why the difference ? If I search for XJ AWD parts I see the proper five holed lower rear control arm is included. Very interesting. I don't think JLR made much difference in the suspension bits under the XF and the XJ, as I recall all of that stuff was carried on from the earlier S Type platform, yes?

Anyway, confusion reigns supreme and I figure some of you might have dealt with this before me so I should ask.My beloved XF is about to be ten years old and with the tragic state of the roads where I live all those bushings are going to need replacing soon.

Thanks in advance!

When I hit a huge pothole and had to rebuild the front right part of my suspension, I had to change #6, #9 and #4. All of three of them had no non-oem counterparts and I had to wait ~3 months from the dealer. Funny enough, I had also bent the steering end link and one from a XE awd actually fit.

 

I replaced the suspension on my 2010 XF with aftermarket parts back when it was easy to order off Rock Auto and EBay. I did match the parts to the OEM but all worked good in the end. The 2014 AWD was a bit different. My front passenger bearing was shot, Jaguar Canada and Jaguar North America could not find the knuckle/hub assembly (You must buy together; parts 4 and 5 in your diagram) and earliest option is ordering from Europe with a minimum 4 month wait. I ordered a front rebuilt pair from Alibaba to keep the car on the road and I'm rebuilding the original ones I removed from the car.
Took a while to track the correct bearing, verifying the magnet spacing for the ABS only to do a quick look and seeing that Rock Auto has the correct bearing at a great price hidden in with all the RWD parts. I purchased the CENTRIC 41290001E C-TEK and verified it was for my AWD with 355mm discs.
When I did the rear suspension for the 2014, I was able to track some OEM and some aftermarket but all parts were the same as what I removed. Making sure the headlight leveler was correct was a bit tricky for my efforts but now I look, it seems more easier to track.
