My 1988 Defender 90 has started making a knocking/rattling sound (sort of a loud tick tick tick) when making hard turns (sounds like it is coming from the front right hand side), this is before it gets to full lock, and when on full lock the pump belt wines.
I have replaced the pump and pump belt and however tight I make it, it still wines. I think this must be a steering box problem, as all else seems ok, I have checked oil levels, greased all that can be, replace track rod end ball joint etc. etc.
I have a steering box seal kit, but before I attempt to fit it I would be grateful of any advice if this is what may be causing the rattling, do you think the seal kit will help, and any advice on how to fit the kit.
Cheers in advance.
