HJ60 - ominous grinding from the front in 4wd

Hello guys,

we went to Abercrombie NP today and went on a nice 4wd track. At some point we almost got stuck. The back wheels were spinning so normaly the front wheels should get us out. But instead of spinning there was a loud and strange metallic noise from the front. I tried the reverse gear and we had the same noise. We were in L4 (and the front was in lock). Any idea what this could be?

Cheers

does it only sounds bad in 4wd?

on some dirt or on the grass try putting it in L4 and turn the steering lock to lock each side and drive slowly
if you hear the crunching sound you could of busted a CV or 2.

how hard have you been wheeling the 60? any times when you have been using the loud pedal when the front end is in the air and then comes down on a high traction surface?

We drove all the time in L4. Without any problem. It was just this one moment.

Could you please explain what to do? :lol: Steering lock = lock the front wheels? Just one or both? Sorry :oops:

Did some easy tracks. On sunday did a difficult one with some guys from this forum. I had the noise there once, too. The time a tried to climb a big rock. But later everything was ok again.

Cheers

lock to lock means turn the steering wheel all the way to the right until it wont go any further, then drive a bit and listen for crunching sounds, then turn the steering wheel all the way to the left and drive a bit listening for sounds.. i think CV's are about $120ish or so to buy new.. the cost will come in getting them replaced.. hope that helps.

sound like you have busted a CV\'s, ceck ebay for new aftermarked ones or repco, wreckers etc, you are best to get with axles as I would suggest you have prolly shaged them as well, the CVs are the same either side, but there is a long and a short axle

if you have some basic mechenical knowledge you can do them yourself, if not the mechenic should not take any longer than an hour a side, we could do them in 15 min a side on the side of a track with air tools at comps back in the day :lol:

OK, I'll check that as soon as I find a place to do so.

We are near the boarder to Victoria. Anybody can help me replacing them?

Ok, sorry :cool: We are in the Kosciuszko National Park. As we want to go to the Victorias Highlands, I guess it's better to have a car which can go 4wd.

If there is someone somewhere around who can help, that would be awesome. Of course he don't need to do it for free.

btw: What does CV stand for? :oops:

Curriculum Vitae

You sure the noise is coming from the front diff?

Could just be the transfer has not engaged 4WD properly. Fairly common with these transfers when worn (transfer lever linkage bushes, I think). Make sure the lever is firmly into 4H before shifting across to 4L. Easier to ensure proper 4WD engagement if you're moving (with hubs locked). Worry about it when it starts popping front drive under load.

I tried it today on gravel and on gras. I heared no strange noise. Maybe juscruisin is right. Is there another check I ccan do by myself or do I need to go to a mechanic?

We crossed Victoria's High Country between Omeo to Mansfield and had not one problem at all. It was an amazing trip with some difficult 4wd. I'm happy that the car performed that good!

Thanks for the help.
