• Leaks around & under windscreen
• Roof gutter alignment/paint/sealing issues
• Brake fluid reservoir rubbing on underside of bonnet
• Faulty air conditioner thermal cut-off valves

why don't you guys go and collect your issues noted and send them to neil@lro.com i reckon maybe we are not getting the best service in the world over here, they reckon that Land Rover sends out letters to owners who may benefit from up-grades has anyone received such a letter ?
now neil did not write this article was called new defender 2.4 issues and solutions and was in August edition of the magazine it would be great to put a piece in from the AULRO collective and see what response we get and weather they have answers regards Andy.

Andy,have seen the article your referring to,we've had afew issues but even over here we have never been contacted by LR regarding upgrades etc.

Hi i am on my 3th rear diff , this one still makes a whine on the float at about 100kms and is quite loud. Any ideas?

There appear to have been manufacturing/assembly quality issues leading to some requiring replacement.

You are having worse luck unfortunately.

Having said that, the diffs are not particularly strong, especially compared to the Salisbury that was used in earlier 110/130's.

In a thread about strength of P38 diffs compared to disco diffs in another forum, Dave Ashcroft posted the following, after someone else commented that the military Wolfe use the P38 diff, so assume it is stronger:

the Military went to the wolfe axle not because the P38 diff was stronger but the axle housing could be strengthened to take a higher GVW, the tubes were coming out of the cast housing on the salisbury,

The P38 4 pin diff centre is better than the 2 pin disco type but the ring and pinion are weaker as the P38 pinion is shorter, ie bigger load on the pinion bearings,

AFAIK the P38 diff was used in later TD5 Defenders and I am assuming still used in the new models.

Edit: I wonder if they might use crush sleeves for pinion bearing preload now, instead of solid spacers - that could be another explanation.

An ARB airlocker should see to that

Hey Guys,
you are making me nervous. All this with a new vehicle?
cheers

only some...

we only seem to get friday arvo and wednesday rovers down here..


FWIW... a lot of the faults in the donk itself are not just limited to the deefer, some of them turn up in the transit van versions as well....


(at least i dont think we inherited the clutch/flywheel problem that Ive heard about)
