If they are leaking make sure it’s not oil getting past the inner axle seal from the diff. I was told my hubs were leaking because of pitting but it was actually oil from the diff as this seal had failed. I had it replaced with a special sea kit from terrain tamer last month, a thousand miles later all is dry
Cheers Ben actually starting to feel like I've put a dent in the work know, a mate of mine popped round on the weekend and gave me a hand. He stripped the interior out whilst I did a bit of painting on yet more chassis parts... got to appreciate it when your mates don't mind giving up a Sunday to offer a hand, just got to convert him from defenders to a Toyota ha ha
Had the same rear wheel arch panels from cruiserworld, they worked well. Wish i had fitted a rubber strip to the lip once they were done to stop stones chipping the paint off Hayden.
Also have a check under the back edge of the rear inner wheel arch under the vinyl cover, a common place to go too.
