Without using google, can anyone confirm the correct part numbers for the 3-4 differential isolator bushes? The only numbers I could find were for the S-type - XR818453, C2C1780, C2C822, XR813260 and XR818452

 

Good Morning Jahummer!

I did a quick search using our parts distributors look up system and found these two insulator part numbers: C2C16377-Differential Mount Insulator & C2C8221-Differential Housing Insulator. Hope this helps!

Additional Notes: Not sure if you need these but this is from our parts look up system we use. Grant it, a lot of parts on here get superseded.

jahummer,
I really appreciate your question and your X358 "Rear Subframe Bushes" post that popped up below.
I've been waiting for mild weather to look for suspension noises. You have provided a lead to a very likely source.
Thank you very much.

best regards,
Bill

 

The rear diff isolators were in stock at the main dealer half of the front diff isolator was in stock. All other part numbers were NLA which I'm seeing more and more for all JLR vehicles.

 

When rubber bushings are NLA you can make your own from liquid polyurethane and hardener. Or purchase universal polyurethane top-hat bushes.
