Hi I am going to take out the input gear next weekend and see what it looks like. I'll run it with the gear out and see how it sounds. Henry

Hi It was already making the noise before the new gearbox went in - the gearbox had other issues (syncro not effective) so I thought I would change it - I thought it might also cure the noise issue - but that would have been far to easy.....! Henry

Hi I am going to check out the alloys as I don't want them falling off - but that really can't be the cause of the judder problem - as it did it even when I had steel wheels on (and the bigger tyres). My gut feeling is that the bigger tyres made an existing issue more apparent. Henry

Hi The release bearings were certainly done - so we can rule them out. I know it is not the wheels/prop shaft etc, as it does it when the transfer box is in neutral - so the propshafts, diffs, output flanges, wheels etc are not turning. I think it is the input gear - it's the only thing...

Hi I have the standard alloys fitted to every 300TDi Disco I ever see - you can probably see them in my avatar. Henry

OK - that could be a problem! The alloy nuts went on easily though and when you spin the wheel, nothing seems to be 'connecting'. I'll check the studs tomorrow. Henry

Hi I would have thought with an efficient thermostat you wouldn't need one. The heater should blow out hot air - I find the air coming from my one can actually make me too too warm so I have to turn it down - even when it is sub-zero. See this for other ways to improve the heater...

Thanks, I'll add this to the possibles then.

Hi I can probably rule out the bucked alloy - as one of my combinations was a steel with 7.50r16 on it and the other side steel with 235x85 - so no alloys involved. This did seem to reduce it a little (and I know that having different sized tyres on the same axle is not good - I gave the diff...

I thought that - but I changed them both - so I would have to have two bucked alloys. AND - I also tried with one side with a steel 7.50 on it and the other side with a steel 235x85 on it - okay, not the best to drive with, but okay for a quick test. i found this combination didn't cure the...

They both did it from brand new......if that makes a difference. H.

Hi Are you getting much extra exhaust smoke? I had an issue with my land rover a couple of years ago. I lost power when driving along the M5 - dropped down to around 20MPH top speed - which was an issue! I checked the air filter - fine - and did all of the basics. Eventually I noticed...

Hi Yes, the tyres are brand new - and I thought balance as well - so I got them balanced. Swapping both front - rear makes no difference. It seems that putting the bigger/wider tyres on and/or alloys is causing the issue (or revealing it). Henry

Yes, new clutch (and associated bearings). The clutch operation makes no difference to the noise. Clutch in, clutch out - it just wines. Henry

I got cold last winter - so I decided to do something about it. My 1989 110 has a 300TDi engine - but the original heater. After making my alterations I now find the heater HOT and actually have to turn it down. And yes, I get air coming in round the doors and through the badly fitting air...
