Reverse, turn -> Shudder?

[JohnBoyZA]

Hi All
I bought a brand new Defender in December 2023 and it currently has 8,500km on the clock. Being new to the world of Land Rovers I have been very impressed. Recently however, I have noticed a vibration on the steering wheel, especially when reversing and turning out of the garage in the mornings (on tarmac). It feels as if the diff-locks are engaging. I sent it in to the workshop last week and this morning the Land Rover workshop informs me there is no fault. fyi. This is in Eco and Comfort modes. I also tried other modes, also engaging low range and various other settings before trying again in Comfort mode.

Anyone experience something similar? Is this normal?

Thank you

If you are turning at full lock, it could be the tyres touching the body work or loose part/s in the wheel arches.

If it has an e-diff, ask a LR dealer to run a diagnostic check procedure on the rear e-diff's operation.

Don't know anything about these particular cars, but am discussing similar symptoms with someone on another place. Reckon Graeme is on the money, as the issue I'm talking about is clutch binding on a rebuilt LSD.

It could also be an issue with the centre diff especially if it doesn't have the disconnecting front drive.

MY23.5 110 is mine, just under 30000km now, have sometimes similar when turning through a tight roundabout or side street. To me it's the e-diff working to get the wheel speeds correct.

I do find that the L663 has a worse turning circle than the old D4, but doesn't have the LCA issues that provided this tight turning circle.

Just an update - they couldn't pick up anything in the diagnostics, but finally admitted there was an issue so they are ordering a replacement rear diff from the UK, should take 4 weeks - only time will tell, will keep you in the loop. Thank you for all they replies and suggestions.

That's great news, and decent customer service too.

I have a MY 22 D300 now with 105000km. Purchased new and no trouble until around 30000km at which point started to detect a shudder whilst towing around 100kph. Dealer tested and said could not replicate. At around 50000 was sent back and a diff count was done and was outside of JLR parameters. New diff fitted.
Long story short my 5th diff has just been identified as needing replacement after 10000km. There is clearly a problem with these diffs or an underlying undiagnosed problem with the car that causes this shudder.
Land Rover Australia have refused any compensation and are at this stage unable to repair my vehicle

You might do well to get an opinion from Pensinsula Rangie. Apparently the proprieter has good success with fixing failed L663 rear e-diffs.
