Lightning Posted August 30, 2007 Share Posted August 30, 2007 I have a vibration on my Defender TD5 at about 25mph and again at about 48mph. I checked underneath and everything seems OK but there is a bit of lateral play in the bearing at the rear of the front propshaft. (I think this is the transfer box?) I took it in to the dealer but they said a bit of play was "normal" and as it is not leaking any oil then it was OK. It feels like propshaft imbalance, but the dealer said they ran it with just the rear propshaft on/just the front one on and it made no difference. At first they said it might be the transfer box but then they decided there was nothing wrong. The vibration is a low frequency one and is not through the steering, it's like on a car where you leave the sunroof open and it causes a pressure wave inside the vehicle. Anybody got any ideas as to what it could be? Or is it just a feature of the Defender...the one they lent me (which had done 5000 miles) wasn't much different.

BogMonster Posted August 30, 2007 Share Posted August 30, 2007 wheel balance? can you feel anything through the steering? a bit of play in the output shaft bearings is not uncommon and probably is nothing to worry about Quote Link to comment Share on other sites More sharing options...
Lightning Posted August 31, 2007 Author Share Posted August 31, 2007 There is no vibration through the steering, but I will get the wheel balance checked anyway, it won't do any harm. I was wondering if it may be the flywheel I believe they can go out of balance. Quote Link to comment Share on other sites More sharing options...
Gromit Posted August 31, 2007 Share Posted August 31, 2007 it may be the flywheel I believe they can go out of balance. Well do the vibrations stop when you dip the clutch? Quote Link to comment Share on other sites More sharing options...
Lightning Posted September 1, 2007 Author Share Posted September 1, 2007 No the vibration remains when the clutch pedal is pressed down. Quote Link to comment Share on other sites More sharing options...
Gromit Posted September 3, 2007 Share Posted September 3, 2007 No the vibration remains when the clutch pedal is pressed down. Well then it is unlikely to be the flywheel. I'd be inclined to go with BMs suggestion first. Try swapping the wheels front to back and see if there's any change. Quote Link to comment Share on other sites More sharing options...
Lightning Posted September 4, 2007 Author Share Posted September 4, 2007 Thanks for the advice I'll try that this weekend and report back. Quote Link to comment Share on other sites More sharing options...
