Grinding Noise Disengaging Clutch After 2" Lift

I'm already trying to find the solution of my problem for a couple of days now but just want to have an opinion about my specific problem.

Last week, I installed a Terrafirma Medium Duty suspension kit which has a 2" lift. While driving home (just a couple of miles) from the mechanic, I noticed nothing special. However, the days after, while taking corners and downshifting to 2nd or when standing in traffic and pulling off from 1st or 2nd, there's a pretty loud grinding noise from underneath the truck just on the last centimeters of disengaging the clutch. It only happens after 10 miles so looks like it happens after it's warmed up a bit. I can't seem to find where it's from but looks like somewhere in the front/underneath seat.

Also, when I'm driving on the highway + 60mph, I feel my footplates vibrating. Not too much that it's dangerous but stil, it wasn't occuring before. The UJ's seem fine though.

Would it be possible that both things are related with each other because I didn't had both problems before the lift. Is this a clutch problem or could it be that I need to install a double cardan front propshaft to fix both problems? My main priority is the grinding noise, which doesn't feel healthy.

Thanks for sharing your knowledge.

Probably one of the UJ's revolting after the lift.
It has to move more now and dosen't like it because of the change of angle and is heating up and seizing.
Feel joints after a run. Carefull one may be very hot.

So you reckon that the grinding noise when shifting in 1st & 2nd is also caused because of the UJ's? The double cardan prop for a 200tdi is a pretty expensive thingy so I want to be at least 90% sure that that can fix it of course
Do they always heat up or is this just a sign of seizing?

Cheers!

They can be warm after a run but a seizing one will be very hot. I do not think a 2 inch lift should trouble a standard prop in good nick. However I am not a fan of lift's.
Others may be able to give more info.

As @tottot said, check your UJ's for excessive heating, and whilst you're at it, give them a good top-up of grease.
