Never took mine off road, no green laning, no fording. Was just driving to work and back. They were properly greased, I know how to grease UJs
. It's just that britpart are ****. My front prop is original from the looks of it and I haven't changed the UJs since I've had the motor and that's been perfectly fine. If you can find my thread its got pics of the yoke which had sheared. Was not a spot of grease on it and it was only 4 months old, no idea where the grease went but I can assure you I definitely put plenty in. I believe the OP did too so agree with him on the ****ness of britpart. Wouldn't buy three in a row though
