Front diff flanges

[theron]

I'm trying to identify a vibration that I'm having difficulty tracking down. I've tried most of the usual suspects (prop UJ's, wheel bearings).

If I remove the front axles (unbolt from diff end, extract from wheel end) are the flanges in the diff held in position - Can I drive the car without the axles in place holding the diff flanges in? I have fixed hubs.

Thanks,

far to much work involved in removing the shafts, and without the shafts in place on the front hubs you will be in danger of the ingress of dirt, far better to simply remove the cap on the fixed hubs and remove the circlip, then undo the 6 nuts and remove the hub, the wheel can now rotate and the shaft will stay stationary, do this on both sides and road test, there is still a small risk of dirt getting into the wheel bearings but if you keep away from water and drive just on dry tarmac for a mile or two you should have no problem, Rick

Good idea, thanks Rick !

Whereabouts are you in the midlands mate? I'm near J9 M6 if you need a hand, I'm free most evenings :thumb2

My 05 makes a hell of a rumble vibration between 60 and 70 mph and can't for the life of me find what it is in fact thinking of getting rid of it , just wish I bought the x trail now

Anything at that speed has to be either wheel bearing or balancing on your wheels

It's defiantly not the wheels infact out of interest I put the back end up in the air removed wheels and spun it up to the speed and still does it, infact I've even removed the rear prop and again spun it up but the noise stoped ?? Can't feel any play in wheel bearing s and even if it was a bearing why would it stop at 70 :doh :doh

Have you tried it with the front prop removed

So if you took the rear prop off and the noise stopped surely it has to be the rear prop?

Yes mate I've done all new ujs as well :doh

Yeah I know what you mean but like you said it could still be a rear wheel bearing or even rear diff ?? Changed the diff oil twice with comma lsd

OK but did you run it with the prop off I've got one of those later props with brand new ujs fitted but it still vibrates as the centre slide is worn

 

[John B]

Do you mean the rear prop ??

 

[cncfabs]

No front but you should check for play in the centre slide as well if its worn will be out of ballance

 

[John B]

I've removed the front prop and test driven and still the same :doh

Ah well it isnt that then

Mine did this!

Took ages to sort out but it turned out to be one of the front propshaft UJ's that was shot but also the front propshaft has a sliding joint on the shaft its self. This sliding joint was shot too, ended up replacing front propshaft with a used one. Easy way to tell is to crawl under the truck and grab hold of the front propshaft and give it a pull about. If you here a very small clicking noise the chances are that's the problem. It's 8 bolts to remove the shaft. If you remove the shaft you can hold at each end and feel the movement in the sliding joint.

Just read some more posts, so does the rear shaft have a sliding joint too?

 

[theron]

The rear prop shaft slides on splines that are in back of the transfer box.

How much play in the front prop sliding joint is OK? Is it knackered if there is any at all?

Sounds that way mate

there should not be any detectable play (up and down) on prop shaft splines if there is then it will lead to out of balance issues without a doubt, Rick
