Well to be honest I was gutted but it could have been worse, i.e. if I bought an IRD or gearbox and fitted them and it didn’t stop the vibration then I would be seriously ****ed off and gutted! Driveshafts didn’t take long to replace and I am sure they will be knackered some day so...

update, new front driveshafts fitted, still exactly the same.

one thing i have noticed today, when the vibration booming occurs between 1500-2000rpm, if i press the clutch in (whilst still in gear normally 3rd/4th) and keep the revs at between 1500-2000rpm then the booming/vibration goes. What does this point towards, any ideas?

Checked for backlash this morning, both driveshafts felt exactly the same, small amount of slack in both. Will try driveshafts next weekend then after that all that is left is the IRD and rear diff.

Brilliant, thanks for the advice, will try that tomorrow as feel I wasted time today as I was hoping to find the problem. I have read all 5 pages of your thread with your L series, when you describe hammering what do you mean, like a drone/resonance through the cabin, I cant really say mine is...

Prop back on now more squeaking brakes but booming worse again with the prop on. Got a driveshaft coming next week, spent today taking off the engine mounts and engine tie rods just in case they were knackered, looked ok, put them back on and on and obviously no different. How do I check the...

Ok thanks for the advice matey, I will try a shaft and will let you know how I get on, will probably try the n/s one first as from reading on the forum this is one that gives the most problem. One thing I have noticed since removing the prop is that my brakes now squeal! Did this when I last...

A lot of people are telling me its likely to be the IRD but if the IRD was knackered surely it would be noisy which it isnt? Anyway as you say it is going to be a half shaft or IRD problem so going to try a half shaft first. Will try the n/s first and if the problem is still there will put the...

From my experience this maybe due to premature cylinder wear due to low quality fuel used in markets such South Africa, Central/South America etc. I would suggest a compression check. Compressions must not be below 27bar (392psi) or have 2bar (29psi) variance between cylinders. If they are...

removed the propshaft today, the booming/vibration between 1500-2000rpm is much less noticeable with the propshaft removed but it is still there (my interior mirror still shakes!). So that rules at the prop/uj's at least, i knew it wasnt the vcu or centre bearings anyway as they had been...

yes a petrol 1.8 one will fit, the KV6 IRD will not

Been looking trying the find the cause of the booming I have through the car at 1500-2000rpm on my L series and it appears there should be a bracket on the exhaust front downpipe which is missing. Could this cause this type of problem? If I am light on the throttle going through 1500-2000rpm...

wow what a long thread and in the end it was a half shaft problem, interesting mine is not really a thuding noise though and it only happens in 3rd,4th,5th gear (barely noticeable in third) between 1500-2000rpm only so in high gears at low revs.

Hello all I have a very annoying problem with my L Series Freelander which I am hoping someone on here can advise or has had a similar problem and cured it. I have a vibration/booming through the cabin which only occurs between 1600rpm and 1900rpm in 4th and 5th gears when there is a slight...

G'day people, im Mick, live in the West Mids, UK and own a 1999 L Series Freelander, just thought id hi to you all
