But TBH, I found very little difference, so put it back on!

The front end has a much more noticable improvement then the rear, and since i run niether it goes alright for a 2" lift

It sounds like something big, and heavy, being thrown in the air, and landing again, like the body coming off its mounts. Noise is kind of metallic. Its been there since I got it 12 months ago. Its not the fuel tank. I had it out last week, and its back in, and very solid in the cradle.

(No, its not something in the loadspace).

I just posted about a similar problem with King springs on another thread. I took some photos of what I think the problem is:

I'm getting a similar noise (I'd describe it as a 'crunch') whenever the rear suspension compresses - especially driving over speed bumps. Try as we might we cannot replicate the sound when the car is stationary, including rocking the car vigorously from side to side and bouncing on the rear bumper. I habe spent time under the car with a torch and everything seems in order. We have a '04 TD5 Diesel with air rear suspension. Dampers are the originals.

G'day all,mine does the same!,only started after new springs and shocks as well,I also thought it was shocks topping out,measured axle drop,was about 90mm,I taped a ribbon off-cut(all I could find that didn't stretch!) to the top of the shock and gave it 80mm slack and taped (only lightly)other end to bottom of shock and marked both ends.Went for a drive and got clunks,but ribbon had not got to even 80mm travel so shocks not the culprit,I've also been told its' the Watts link bushes,so I'll watch this thred with interest
Cheers Gregg

Are you certain they are King Springs?

I have never known King springs to do a Discovery or Defender coil that isnt ground at that end...

Can you confirm they are King, or were you just told they are from King?

The latest development on my shock absorber issue:

They are certainly King Springs +2
The springs aren't seating properly, (beginners mistake....), so facing the fact that I'm running out of time to prepare for the big trip I called the services of my trustworthy mechanic. This is happening tomorrow the 10th April.

Regarding the CLUNK noise some of us are experiencing:

I also mentioned to him a clunk that was there before and still exists after the new suspension being ....."installed". It feels like it's right under your foot, and sometimes also at the rear. I notice it more in wet weather, coming out of the driveway, sometimes driving along when there is a bit of suspension movement or coming to a halt and taking off.

The diagnoses from the mechanic is that it's the bushes from radius arms and trailing arms. This is apparently a common problem with a simple solution,....replace with new.
Well, the bushes from the old shocks looked like pancakes already, so I'm not surprised that other rubber is reaching the end of their life span.

My immediately question was......have you got Poly bushes ?
His opinion is that I better off put original rubber bushes, his opinion is that poly bushes aren't very good for this type of vehicle.
I'll find out the reasons behind this tomorrow and let you guys know.

Thanks for that...

Well the good news... Your springs are wrong and that's why they are binding up front!!! The front are supposed to be ground to flat up top in the front and pigtailed at the bottom on a D2.

What part number is printed on the coils?

Trailing arm bushes on D2s rarely fail.
More likely the Watts link or sway bar links.
