I have had a condition (if it is one) on my Paj for a while now, but the Marcuskraal trip just highlighted the issue a bit further to me.
When in first gear I have what I can only describe as a gentle, "thrum, thrum, thrum", slightly high pitched, which seems to come from the front. It happens in 2H all the way through 4Hlc, although possibly louder in 4WD.
It doesn't seem to happen in the other gears.
Any ideas?

only thing I can think of is the first gear syncro ring might be worn.
I hope I understand the noise.
If it sounds like a tin can rattling, check the dust flange over the tail shaft at the end of the transfer case.
They often come loose (it's just a press fit).
Check it in any case.

No definitely not like a tin can... but will take a look anyway.
It's more like a cyclical hum, the frequency of which increases as the revs increase, although the pitch doesn't change

Then I would imagine that it would happen in all gears? Not just first?Scubadude wrote:Worn propshaft universals?SimonB wrote:No definitely not like a tin can... but will take a look anyway.

Not quite ... worn UJ's typically make that low speed drive train rumble, more noticable in first gear at first. I once rebuilt the propshaft on my Colt due to low speed drive train drone and "quick judder" on rapid take-offs. Could not believe how a R 1500 job transformed my driving experience ... not only at low speeds but also while cruising. Could also be the propshaft itself that is running out of true (they balance the shaft when rebuilding in any case). Either way, take it to a prop shaft shop, they'll check it out in no time. If they find a problem be glad its a quick and relatively inexpensive fix.SimonB wrote:Then I would imagine that it would happen in all gears?
