dull groan/vibration sound

Strange one here as i cant pin the noise down

Iv got a 300tdi 2" tf lift and 2" body lift 33" tyres

Now iv started getting a new noise but it doesnt alsways happen,
but when it does its at low speed usually over speed bumps or when i drive off of a kerb where i park the car,

happens going forward or backwards.

sounds to be coming from front drivers side, but i cant replicate it with car jacked up.
its kind of a dull vibrate groan like sound but theres no vibration through the steering or pedals

Its not the bearings there all good,

So has any body any idea, im going to re grease props to rule out that, my other thought is front swivel as it leaks and is slowly getting worse so packed it with the grease you get instead of oil.

check ujs and try it with front prop off

UJ's should be fine swapped em other month after a minor issue lol, will double check wm again though

Sorry for sounding really stupid but I'm a complete novice! What is a UJ?
Trying to solve a similar issue with my Freelander!

Freelanders are different, go to the Freelander section and read up on it

Oh, 'UJ's are universal joints

Sorry my bad!
And thank you

Brake backing plates. Prop bearings might be tight to feel have u tried tightening then and related test.

CV joint? does it happen in straight line or when turning?

I have a disco 2 and I get a similar sound. Going over bumps or curbs. It's almost like someone pinging a ruler on the edge of a table. Any one any ideas?
