Confirmed today that my 110 Utility with heavy duty suspension has light duty 2 pin diffs. When I ordered the vehicle I was not given a choice between 2 or 4 pin diffs. Clearly the 2 pin is not strong enough for a loaded 110 thats used off road as a work vehicle. I am waiting for LR to advise me as to what they intend to do to fix the problem.

I also have a new 110 XS CSW waiting to be collected. I have asked the question 'So what diffs are in the new one then guess what they don't know I will take delivery of the new vehicle on the understanding that 4 pin diffs will be fitted if its found that 2 pins have been installed originally.

Hi,

all Puma 110 rear diffs are TBB000270, this is a 4 pin type, short casing like the P38 RR.

the front is a 2 pin TBB000250 but can be replaced with the 4 pin type TBB000280,

the 2 pin won't last long off road, wheel spinning kills them, not a power issue, they last better with traction control as this reduces the wheel spin, Dave

common yes, normal no,

I am told Landrover are having big diff noise problems on new builds as they have changed the heat treatment plant for the ring and pinions,

tell the dealer you want it fixed, they should not whine at all, the 2.4 90 diffs are the same as a series 2 disco and they didn't whine, don't be fobbed off, Dave

Thanks Dave, thats the thing though I won't be fobbed off! Somuch so I have here a letter from land rover with a report on my vehicle. On one of the 6 major points I complain about he (the engineer form lr) said the diff whine is quite normal. I will scan it at work on Monday.

The LR engineer is an idiot.

I have a slight drive line clonk (not a normal one) the engineer said its ok - maybe something but as my 90 hasnt covered enough mileage it could be ok could be serious. Net result LR think its fine.

Im concerned if the diffs are weaker i may not experience it for years. Mike

I also have driveline clonk in my Puma, but I wouldn't call it slight. The Land Rover technical chap says this is also normal, even to the point of saying "it's characteristic of the marque sir". I'm still persuing the issue, but LR have thrown it back at the dealer saying my complaint/contract is with them. I can't help thinking that LR have a number of problems they don't want to fix!

Just joined the forum - this is all very interesting (read: potentially worrying...).

I've also got drive-line clonk. More than slight, I'd say, but not sounding anything like terminal, so again, i assume the dealer will use the 'feature not a fault' line. The demonstrator that I drove back in March had the same issue, as did the TD5 that I bought instead - but that's another story...

Be interesting to hear from anyone who's succeeded in getting this accepted as a fault and rectified 1953 80
