Got a whine in the 80 can't pick it thought was the diff, changed diff center whine still there not as bad as before i changed it,also changed wheel bearings.

noise is real bad at 80 km, before and after not bad at all

any ideas would be great

may sound dumb but have you fitted roof racks lately ?

could be dry unis also?

Swap tyres back to front...thats if the noise is not coming from the passenger seat

Does the 80 have a centre bearing ???? could be this.

Just a thought

no centre bearing. i would be looking at uj's, diff centres and wheel bearings

Had a arb roof rack for ages. Just put on new tyres, bfg muddies. Diff center was just replaced with a reco one cause i thought that was where the sound was coming from, and replaced the wheel bearings at the same time as the diff. all ways grease the uni's and i changed the gear box and transfer oil there was no water or mud in that.

The noise appeared when i got bogged up to the head lights in a huge bog hole.

what about bearing noises in alternator or a/c?.

Don't think so but i will check it out the noise is at about 80 or really noticable at 80 any way.

sound like you have a serious problem, you have picked up my ex-wife. She is a big mud hole...................

better get rid of it quick, or it will cost you a packet...........not to mention your sanity.........

look what it did to me...

ha ha that explains it all the old hand brake trick your nothing but heart ache and suffering poor old hip pocket

Make sure centre diff lock is dissengaging ,they're elelectronicly controled and get grumpy when exposed to mud and water.

NAH part time hubs She's not a gxl But cheers for the thought

Pull the rear t/shaft out and test drive it using front diff' the front might give a few more noises but you should be able to isolate the original noise a bit more. Does it vary from load to no load or stay the same?

Had this before in a constant 4wd 80 and it was the front diff gears, find someone with a set of steelman chassis ears and clip them to the front and rear diff and also the gearbox and transfere case, if you switch channels to the respective components you'll soon find the noise, if its at 80 ks it will likely be diff gears, bearings generally are noisier on corners as weight transfers.

Currently building a tray middy 5.7 Gen 3 and TO4ZR turbo, ditching the gas, it's ace but I want to do longer events and carry jerries.
I'll be running the All4 colors and Peninsula Per4mance as this is the new wing to PGS where I'm running the new 4wd dyno.

Real sorry to hear about Jim, all the best from me if you speak to him.

Had an 80 series at work with a whining noise that sounded like gear noise. Was there in every gear.

Car yard took it to gearbox shop and they said it was the clutch, and it had a petrol clutch fitted?
80 series is a diesel with a 1HZ.
Will let you know the outcome.

noise is pretty constant with or without load afer puting new diff center in it's still there but seems to be getting better.

Can the diff wear in like this or am i getting used to it....

Gettin used to it Id say, generally diff gears are worst around coast at 80 to 100 klms.
