My rear diff is knocking when I pull off ! So have decided to fit a secound hand axle !
So just wondered will a 2011 rear axle fit my 58 plate nav ?

It should be fine as both are 2.5 engine models and that you are not mixing an automatic gearbox version on a manual and vice versa.

are you sure its the diff??????

are you sure its the diff??????

Description sounds like a broken halfshaft to me??

 

[sheepy]

Or just a uj on the prop??

Very good point and a hell of a lot cheaper and easier to fix :fingersx

How do I check for broken half shaft ?
Uj and prop look ok to me !
It only makes the knocking noise while pulling off and you can hear a whistling / grinding noise but only faintly at 60mph ?

If the rear diff was goosed (like mine) you'd really know as it's gets worse with speed.

Also gets worse with time very quickly....

Spray your UJ with WD40 then drive it. It wont remove the knock, but any grinding/squeaking should be gone for 5 minutes or so.

I may have a look inside it to see if I can see any think wrong with it?
Has any one rebuild a diff on here?

 

[lookskyward1]

Do a full inspection of both the propshaft(s) and their UJs before stripping anything down. Jack the front and back up checking the drive system for any slack. The cause will probably be obvious when you spin a wheel.

Pulling off the rear plate from the diff may show if there is any broken bits.

To remove the diff from the axle you need to pull out the halfhafts anyway. If one is broken it will be obvious.

Rebuilding a diff is quite an involved process that I would leave to a specialist. If the diff is knackered the used axle may be the easiest option.

Good luck and keep us posted

Check your oil level,
check your rear wheel bearings for noise/play (handbrake off & front wheels chocked)
Check uj's (grab/lift/twist in 4 directions)
Check play in diff bearing
Does the noise alter on acc/over-run?
Does noise alter on cornering?
Any oil around or in the rear drums?

As eddmurphy explained, it will die very shortly if the diff is knackered.

 

[Delphi]

Oil is ok ?
Did notice seal looks wet wear prop bolts on ! Noise doesn't change on corners or deceleration ! Just pulling off and changing gear !
No oil round near drums !
How do I check bearing In diff?

Are you even sure it is the back axle? Noises are hard to pinpoint, for example the dodgy dual mass flywheel can make odd noises.

 

[Delphi]

I'm 99% sure it's from the rear end

 

[Delphi]

Had a better look at the axle tonight and took some photos

 

[Delphi]

Pic of oil drain small amount of metal

 

[eddmurphy]

That's not small parts mate. That's quite big chunks of something.....

 

[landmannnn]

Looks like your diagnosis was right , diff buggered.

 

[Delphi]

I think the pic makes it looks a lot worse !
