Grinding when reversing, is this normal?

[Hellsbells]

Hi, just after some advice. We test drove a fab Bongo today and all is well and she is in great shape. How ever when I reversed her back and turned the wheel there was a grinding noise, front passenger side and felt juddering is this normal for the 4wd?
She has had the bottom ball joints and track rod ends replaced, anti roll bar links and the steering rack gaiters. She does have 17 inch alloy wheels. Any advice would be great.

Welcome!
I seem to recall that people that replaced the wheels with larger ones had rubbing problems on full-lock of the steering could that have been the issue ?

May be the front disc backplates touching the discs. They are quite flimsy particularly if rusty and fitted close to the discs. If someone's been replacing ball joints and trackrod ends it's possible they've accidentally disturbed the backplate. They do flex a bit with the steering, mine were quite rusty and had to be flexed around to clear the disks when bumped after replacing the wheel.
I don't think this is the cause of the judder though. This may be as serious as a problem with the clutch on the reverse gear in the gearbox or as simple as one wheel slipping on the ground on lock

It could also be the CV joints/s " Constant Velocity ". You could also ask the seller for any information on the problem.
