Hi to you all.
I have just joined the forum and am pleased to be a member.
I have a V6s that has 19000 miles, year 2015.
Bought it last year from a dealer (not from a Jag dealer).
A few issues but I absolutely love this car.
I just took it to my local mechanic who is A1...one of the best.
I have a small oil leak on the rear differential, so I asked him to drain and refill so that I can monitor the leak...got him to add an approved sealant added to the oil, we will see if this cures the leak.
On collecting my car today, he told me of excessive corrosion to the rear chassis, unfortunately he didn’t take any photos whilst it was on the ramp. So I googled and found your helpful forum where the problem is identified as poor quality steel used for the rear subframe and straps/braces etc.
I must say, as a degreed metallurgical engineer, I was amazed to learn of this issue on a Jag!
But I see this is indeed a proven issue on F types.
So I have 2 questions for you:
1. Any idea of the price to supply and fit new parts

2: And regarding the differential oil leak, another proven issue on the F type, cost to supply and fit a new differential seal

I had better start filling up my piggy bank.

Regards
Clive

It's not actually poor quality steel, it's poor quality anti-corrosion coating.

Part numbers, if you want 'em from "SSM74031 - X152 Under body brace corrosion" (no idea on prices):

T2R 3166 (remove) - Body Brace
T2R 40865 (replacement part)

T2R 18759 (remove) - K-Brace
T2R 40866 (replacement part)

V6/AJ200 variants:
T2P 1597 (remove) - Pt 4 Brace V6/AJ200
T2R 40657 (replacement part)

V8 variant:
T2R 3438 (remove) - Pt 4 V8
T2R 40658 (replacement part)

Welcome to the forum!

I would be having a closer look at them first as it may be possible to just remove them and get them cleaned up, treated and painted/powder coated as others have done.

My local independent was happy to put mine on his lift so I could have a good look around underneath and check, without charge. Maybe you have a local friendly place that could do the same?

My car has the later ‘improved nickel plated’ parts and was already corroding when I got it, so the newer parts aren’t much better. I have treated mine and they now look as they should.

Could be much cheaper than replacement

Many thanks for your prompt reply, I’m grateful.
I will jack up the car and look for myself.
Can you tell me how you treated your subframe, I.e. Waxoil? Paint?

I used a product from Bilt Hamber called Dynax UB. It comes as a large spray can of anti-corrosive wax which dries quickly to form a dark brown hard firm film. It can be applied over rusted or painted surfaces.

If your diff is leaking then think very carefully about putting any form of additive in to seal it. These diffs are so tempremental to type of oil and exact oil levels.

Thank you. I used a Castrol gear oil as Jag recommendation and a sealant addition to the oil. I think about 7.5%. Metered exact quantity into the differential. It was not a big oil leak, drained about 700cc of old oil. Car has done 19000 miles. Apparently the sealant may work after a few hundred miles, time will tell. If it works I will post a message. I reckoned it was worth a try, fingers crossed....

They accepted and the full subframe and braces were replaced by my local Jaguar Dealer. I went to Switzerland with a nice new subframe and braces fitted at the end of May.

Job done.

Anyone else with the same problem keep pushing.

Fabulous car for touring the Swiss Alps.
how much were they charging for the replacement parts
