Vibration at approx 1750 rpm?

Hello
Thanks for the advice, decided to change the bottom mount anyway, new one has a weight on it? removed the sump guard and found the exaust support bracket fractured all the way round where it is welded to the pipe, looks like it had a botched welding job on it previously. Fitted the new mount and rewelded the bracket. I did a crap job as well, will do it properly when I do the head gasket, drivability vibration seems better, although I have not been far in it yet. pictures attached of new mount and broken exaust support bracket. see yaa

Could Be Front Mounting On Rear Diff,thats The Most Common, The Other 2 Don't Seem To Fail.

How wrecked do I feel. After Tiny suffering the L series vibration at low revs on acceleration peoblem I have at last sorted it and it was Sooooo obvious!! After a good look at the front pipe mount there appeared to be a crack (yep - that simple). After removing the bolts the entire bracket fell off (done well for 160,000+ miles). Being the tight arse that I am I did not want to fork out for a new front pipe so purchased a nice peice of iron from B&Q, cut to size, drilled holes and bolted it to the remainder of the engine bracket. To secure it to the front pipe I used a standard exhaust bracket (the type they use to connect back boxes). Test driven and guess what...no vibration or horrible tinny buzzing sound. Take heed L series owners - if you get a vibration and buzzing at low revs that sounds like it has nothing to do with your exhaust - undo the bracket 1st!!! Yay - Tiny driving like new once again

mine does the same so if you find out what it is let me know please

Erm...as above?????

Hi, i have a similar problem on my 98 1.8 petrol. I havent done an imense amount of investigation, but i recon its to do with the prop shaft or the IRD suppot mounting Bracket that is fractured. Anyway, as i have had enough, i'm brining it to LR dealer to check out. i'll let you know if they find anything.
