Only thinking as like any CV joints it'll wear eventually but at £260 odd, lot of money if it's not common to replace.
I only removed some of the old grease and repacked new lithium grease in there. My car is close to 100k now. There's zero noise from the drivetrain even though by hand I could feel some play in the CV (if normal or not, I don't know).
Cheers, I'll leave it then, I'm pretty much same mileage.

I would definitely do a shifter rebuild while you have easy access to that assembly. From experience, don't bother going with anything other than OE bushes even if the price of the oval bushes are hard to swallow. Not even the fairly expensive Powerflex bushes I got fitted correctly.

Ah ok, sounds like a good idea. Do you know what part numbers are needed for the job?

Through the seller, yes. Seller said he would contact PowerFlex. I made the linked video for the seller to send to PowerFlex. He refunded me, so I didn't chase him.
