Wirrrrring sound - 95 Lux, solid axle.

Post by **Milamber** » Tue Aug 24, 2004 8:41 am

Hi All,

When I reach around 60km per hour a wirring noise kicks in, sounds like it is coming from toward the rear........ It also seems to occur only under load, that is, if I take my foot off the accelerator it goes away and if I drop back down to say 40 kms per hour it goes away............ I am stumped. It is like the sound only occurs at a certain vibration frequency or something.

Any thoughts? The truck is lifted around 2.5 inches and running 32inch tyres, has fresh diff oil and just greased the unis (not sure how to check for play though............................)

Diff? Tailshaft balance? Unis?

Sounds like it may be either the centre bearing or a uni.

To check your uni`s lay under the car on your back and try to push the tail shaft up and down if it moves seems loose near the uni`s you may need new uni`s. As for the center bearing i not sure how to check these`s so can some one explain how as i`d like to check mine aswell

Sounds like what my wheel bearing was doing b4 it went.

Would a stuffed wheel bearing also cause one of the front hubs to be stiff (really stiff) when turning it from free to lock (or vise versa)???

Nah, I don't think so, I'd have to check my Gregory's manual but it may be due to a build up of crud in the hub. Only a not to well educated guess.

hey wilamber......just had to replace all uni splines....3 weeks ago...same sound.. again get the rig and have a look at the splines and there are little surclips that hold the uni centers in place if the joints buggered these will be worn...if u can see that take one end..say the one from diff flange off and make sure the uni moves freely and with rough or stiff move ment if its as described above replace the centers...around 50-70 bucks

cheers

I had a similar noise in the front of my 60 series (so far front it sounded like the fan was rubbing) when I was gutsing up one of the hills at rover park a few weeks ago. As with your issue it stopped when I eased off.. I had heard the noise a few times and it was definatly louder the harder I drove.

I already had my car booked in to have a lokka fitted (good thing I chose the front).. My diff was well out so it went off to the diff lappers who noticed some irregularities in the pinion seating/alignment. They reckon this could probably be the cause of the noise.. My diff had been reconned before I owned it and aparently the work was not too good.

I sure hope this was the cause, I'm off for 2 weeks holidays soon and I am feeling a lot better now the mechanic has had it all apart. Just got her back so its time to get her dirty this weekend hopefully she wont cry when I drive her hard again.

Good Luck..

I had the same thing two weeks ago and just got louder and louder. Pinion bearing!! Luckily it seized just as I was going into my drive way.

Very costly. The centre bearings are also fucked and the diff lapping place found a crack in the pinion.

GET IT FIXED NOW!!! before you fark it like I did!!!

Thanks for the advice all. I had it checked out on the weekend.......... the unis are stuffed (stiff) and need replacing.......... they want 300 bucks to do all three, but at 22 bucks per uni I think I might try it myself.
Is this an easy job?

From a bad memory, I did my commodore ones years ago and I think it was just a couple of circlips and a bit of nudging with a hammer.

I use to drive a 40 series which did exactly the same thing, whirring noise coming from the back, not long after it started making the noise the front wheel dissapeared into the darkness :shock:

It only sound like it was coming from the rear.

Hiya,

Tomsoffroad, what do you mean? Did the wheel bearing grind itself to a pulp and let the wheel disengage?

Eliteforce, I am in Melbourne. I'll take a look around and try for a better price! Thanks.

Post by **tomsoffroad** » Tue Aug 31, 2004 4:32 pm

I'm not sure exactly what happened, when I found the wheel it was still bolted to the drum, the short shaft and bearing tube (carrier) was never found, it was strange cos apart from the noise there was no play in the steering or anything.

I had the same symptons when my pinion bearing went in the rear. It could be one of a few things, better take it to a reputable mechanic.
