I am trying to track down a rattling noise that happens over bumps, and two shops have ruled out ball joints, control arm bushings, sway bar end links and internal strut noise. The car underwent a brake job (in addition to repairs for pothole damage) and this problem surfaced immediately after the repairs.

The noise goes away if lightly touching the brakes. The anti-rattle clips are firmly in place.

My question is, has anyone heard of these bushings going bad and causing rattling noises? Also, is the correct part number for the front bushings for '07 XKR C2C29161?

 

After reading this thread, I'm also thinking the problem could be that the shop did not install the proper backing plates on the back side of the pads as well, I will have to investigate but it is hard to see in there without actually removing the caliper. At this time, I having trouble sourcing a 9mm hex socket so I have ordered one on Amazon.com.

If it goes away when you tap the brakes I suspect it is a loose brake pad. Especially since they just did brake work .

 

I responded to your other post.

Guides are a possibility. If you replace them, just get a new set of pads. They're cheap enough. Get something high quality.

 

The pads are brand new (with under 200 miles on them now)--and they are supposedly genuine Jaguar pads.

Anybody have any idea what the correct part number for the caliper slides themselves are, for the front pins? I'm not sure whether I should order them just to have them on hand in case it turns out they are bad as well.

 

Actually, now I'm reading this thread on the X350, which I know shares a lot of similarities to the X150.

The symptoms sound exactly the same as mine. I wonder if the problem could be part # C2C41632, "Caliper Mount Retainer Spring" and this seems to have solved this guy's problem. Where is this spring actually installed?

 

I am very confused--looking at the diagram on Jaguarparts.com, it seems like C2C41632 is the same as C2P12427 identified on this thread here:

Also, should my caliper be moving this much when I pry on the pads with a screwdriver with moderate force?

 

Following up here, both sides actually move about the same amount when I pry on them with the screwdriver, so I don't think that really tells me anything.

 

Can somebody with an XKR verify that your brake pads in the front have this gap between the caliper bracket and the pad itself? Seems odd to me. Also, any indications in this photo that this may not be an OEM brake pad?



I am a little suspicious because of the "JUR" clearly written on the pad. I searched "JUR brake pad online" and I eventually got this:


Was Jurid the OE manufacturer for the pads?

Here is a photo of Jurid pads with these same markings, which makes me think these are not Jaguar pads:

 

I just looked on Partsgeek.com for the 2007 Jaguar XKR.

The shop originally said they installed "Textar" pads, saying that they are the OE manufacturer for Jaguar and they should be identical other than the branding. Textar pads are listed at $109.48.

As a first attempt to fix this, I ordered the shop to use genuine Jaguar pads (and I paid them an extra $150+ in the price difference for parts), in order to eliminate the possibility that it could be a fitment issue with the pads. However, clearly "Jurid" pads are installed. Jurid pads are listed for $55.73!

What I'm thinking is going on is Jurid pads were installed on the car, and poor fitment and/or lack of OEM style backing plates/shims is causing rattling issues. Furthermore, the shop lied to me when I paid them to install Jaguar OEM pads, and have been playing dumb, while meanwhile I have taken it to a second shop and wasted money on things like oil cooler brackets, new front struts, etc.

Of course, this is all assuming that Jurid is not the OE manufacturer. What do you think?

 

It is hard to say but here is a video of mine.

 

Mine look the same and are the same make. From memory, they were imported by my mechanic from the UK from one of the after market suppliers but could still be OEM spec.

Mine don't rattle though.

 

Thanks for doing that, that seems about the same as mine. Can you tell on the other end of the pad, does it say "31066"?

Also, I'm noticing that my front rotors do not have any sort of markings along the edge. My rear rotors (OEM) have a Jaguar part number and measurements for minimum thickness, etc.

My right side doesn't rattle and it has the same pads on it.

 

I can definitely see 3106. If there is a second 6 it is behind the caliper.

At first glance I thought my front rotors had no markings on but I think I can very vaguely see some light markings. I can't make out what they say though.

I suspect my rotors are the originals as the car has only done 30,000 miles and I have owned it since around 15,000.

 

I meant to say that I had the pads changed on my X350 by the selling dealer when I first got it and became aware of a really bad metallic rattling sound echoing off buildings when driving through the city. That turned out to be missing anti rattle springs so my local dealer put a new pair of pads on for me.

 

If I am not mistaken, anti-rattle springs are part of the pads (i.e., if I ordered OEM pads, it would come with the springs)? I don't see a separate part number for anti-rattle springs.

 

I haven't taken my brakes apart but judging by the workshop manual, the anti rattle spring is part of the logo plate and is listed as C2P12427 in the parts manual for the XKR.

 

Yes, I'm "that guy" and the anti rattle springs on the X350 are different. That thread doesn't apply to your vehicle.

 

The shop (the second shop I've been dealing with, not the one who installed the pads) is telling me that Jurid is one of the manufacturers of the OE brake pads. Is this the case? I can't find anything about it relating to Jaguars.

My question is, is it even worth trying to install genuine OE Jaguar pads, or is this clearly not the issue? If I believe shop #1, they installed Textars first, and then installed Jaguar OE pads (which apparently they went to a non Jaguar-branded OE equivalent). If this is not the issue, the caliper guide pins and the caliper bushings are the only remaining suspects in the brake system.
