Hi all,

Just returned from trying out the new camper trailer on Bribie Island - had a great time. However I noticed that my GU Patrol (4500 petrol/gas) makes a nasty thump or clunk in the driveline every so often. It's quite irregular; it happened most often in 4H on hard, fast sand - might happen every km or two. It felt to me like it could possibly be the transfer case chain jumping a tooth - is that possible? I did take a tape measure to my tyres and discovered that the fronts are 10 mm bigger in diameter than the rears (much newer, same size but different brands) so I suppose a bit of windup is possible, but I wouldn't have thought it likely on sand??? The other thing that seems weird is that it didn't do it when I got bogged and revved the guts out of it, backwards and forwards trying to get the camper out. (Ended up getting snatched by a Jackaroo, how embarrassment! :-)) Any thoughts, anyone?

Regards,
Tim Z

The auto hubs can do this I hear.

Hi Notso,

The auto hubs were my first thought, so I locked them manually, but the problem still occurred?

Just tried to get onto that forum, looks good but I can't register - tells me I have to enter a code from an image for verification, but the image doesn't appear?

I'm not sure how that code works but on some sites there is a link to click if the code doesn't appear.

i would be inclined to think your hubs are jumping have had the same problem with manual hubs on my GQ, went through the whole thing checking the hubs no marks on the spline so thought they where fine, checked and greased drive line, finely got to transfer case, and bought second hand job fitted it and still had same prob, ended up replacing hubs and problem fixed. Then had to change transfer out again due to oil leak very expensive lesson, hubs are really cheap. Col

Thanks very much for that info Col, that's really helpful. Will definitely concentrate on the hubs first!
