Grinding when 4wd is engaged

I've noticed that when i engage 4wd there is a grind noise coming from somewhere - when i dip the clutch to engage 4wd on the move it grinds and when traveling in 4wd it grinds intermittently I had a replacement axle put on this time last year after it was grinding constantly when i 4wd (it was so bad i thought the axle was about to rip itself off) - then it turned out to be a nackered diff :sick: :sick: Any body got any ideas as to what it could be? It only does it when the clutch is dipped and when the 4wd is engaged. I have noticed that if i switch to 4wd before starting and drive it doesnt grind, only when its been running for a few miles does it start to do it.

Hello mate, I had a loud grinding from the front end every now and again which eventually became more and more. Sounds similar to that what your saying. Someone suggested one of the hubs was engaging on and off causing it to grind while driving. I had the king pin bearings do e first then my 4wd broke so have now got manual hubs on. No noise now at all. Maybe same story with your

ive had one king pin and swivel done in the last 4 months, and thought the other side had started to go, but the death wobble stopped, so i haven't worried about too much since. I did think it was the hubs last time but the garage stripped the diff and it was knackered - they didnt do anything until id been down and looked at the inners - it was well past saving. Im tempted to get some free wheeling hubs, but need to wait until pay day now

Well im not to sure what it was but its stopped now. I too only had one side done of the bearings and sure now I need other done. I picked sone hubs up on here for a good price....but its all money aint it. I have a snorkel sat here waiting for pay day to be fitted too! Good luck finding problem though

I have noticed that the noise doesnt happen below 30mph and doesnt happen in low box either. Did your 4wd light flash when your hubs went? Mines still saying on all the time atm

It started like that then got worse. The light stayed on as normal at first and eventually after a few weeks started flashing. Every now and again it would stay on too. Id had enough so bought hubs and had vac system blocked off. Works sweet now mate
