Another vibration question

(1/4) > >>

Leigh:
I'm trying to find the souce of a vibration under the car. To start with it was like a droning noise not too different to mud tyres but its now developed into a metal sounding rattle. I get the droning noise when I push the accelorator and then get the rattle when I release it but stops completely when I push in the clutch. It only happenes when I'm moving and at all speeds. Could this be the bearings in the UJ?

I've checked the props and there is some movement in the UJ at the transfer box end. I can also turn the prop a little by twisting it before it engages. The rear doesn't have any movement at all.

While under there I also noticed what looks like an drain plug missing in the gearbox bellhousing. There is oil in the hole. I've taken a piccy to show you where I mean. Any idea what this hole is for and should it be blocked?



Cheers

Budgie:
The hole is to drain any oil etc from the bellhousing, it only needs to be plugged when you intend to go playing in the water.
You'll also find one on the underside of the timing belt casing, which should also be open.

If you don't have any plugs then you can get them from most Land Rover parts places.  :wink:

Like I said in the PM, I think you've got a U/J gone on the front propshaft.  :wink:

Range Rover Blues:
The rear prop doesn't move because of the handbrake, the front one does because of the play in the front axle.  That's normal.  Think you might have a UJ going though, it happens when you lift them, probably the gearbox end.

Leigh:
For a minute I thought it might have been a drain plug fallen out and I'd lost all gearbox oil and the moise I could hear was my gearbox grinding away  :lol:  :oops:  :lol:  :lol:

Thanks for the help, I'll order a new UJ tomorrow. The movement is on the gearbox end of the prop. Is it a good idea to replace both ends at the same time??

Cheers

If the other end is nice & tight then I'd leave it be for now, no point in changing it if it's still good and it could last another year or two before it needs doing.

I would grease it & the centre splines tough.  :wink:
