I agree Dodgeman. I think that most drivelines suffer when introduced to shock loadings rather than horsepower applied in a linear fashion. The H145 and stock 4 speed still function (touch wood

) despite a bit of curry !! I use a good oil in the box - Castrol Syntrans M (has a new name now I think) and make sure any driveline slack is taken up by the clutch before letting it loose

.Despite H165 and even H190 being stronger, the axles are still not massive so one still has to be aware that extreme shock loads will soon find any weaknessess in any system. Component upgrades are good - common sense is better

.
Cheers
