Death Wobble Vibration THIS MAY BE OF SOME HELP

:rolly:
TD5 03 model 18" wheels Pirelli Scorpions 110000 miles
Over bumps lots of shake rattle and roll.

Ist the shocks were changed to these Bilstein Shocks for Land Rover Defender, Discovery and Range Rover from RoversNorth.com

Next the steering damper was changed to this

Tracking done along with wheel balancing

Total cost including parts labour V.A.T. 355

Result:- Handles and performs like a dream,no shake rattle and roll.
Over bumps now there is a minute THUD

Both the shocks and damper incorporate Nitrogen Gas

[FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1][SIZE=+0]Gas Shock Absorbers [/SIZE][/SIZE][/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]Gas shock absorbers represent an advance over traditional shocks. At high speeds, the flow of oil in the cylinder can cause a foam of oil and air to form. This limits the optimum throughput of the flow in the valves. The addition of nitrogen under pressure limits this phenomenon and increases efficiency. [/SIZE][/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]There are two types of gas shock absorbers: [/SIZE][/FONT]

• [FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]Single tube with high pressure [/SIZE][/FONT]
• [FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]Twin-tube with low pressure gas. [/SIZE][/FONT]

[FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]1. High pressure single tube shock absorbers. [/SIZE][/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]Gas shock absorbers operate on the same basic principle of movement of the piston in an oil filled tube but they contain, at one end, a small quantity of nitrogen under high pressure (25 bars). [/SIZE][/FONT][/SIZE][/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]The gas is prevented from mixing with the oil by a floating piston. When the piston rod passes into the body and displaces oil, the oil compresses the nitrogen even further. The volume of gas changes, playing the same role as an equalization tube. The permanent pressure exerted on the oil by the gas guarantees an instantaneous response and quieter piston valve operation. At the same time, this constant pressure eliminates cavitation and foaming which could momentarily degrade the effectiveness of the shock absorber. [/SIZE][/FONT][/SIZE][/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]2. Low Pressure gas twin-tube shock absorbers[/SIZE][/FONT][/SIZE][/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]The Monroe Original twin-tube Gas-Technology design retains the classical twin-tube while adding, at the top of the reserve tube, nitrogen under relatively low pressure 2,5-5 bars instead of the 25-30 bars used in high pressure shock absorbers.
This pressure is sufficient to to radically improve the efficiency of the shock absorber. [/SIZE][/FONT][/SIZE][/FONT][/SIZE][/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]The Monroe Original low-pressure design presents two main innovations: [/SIZE][/FONT][/SIZE][/FONT][/SIZE][/FONT]

• [FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]
  [*][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]in the upper part of the reserve tube, air at atmospheric pressure is replaced by nitrogen ( an inert gas) at pressure of 2,5 to 5 bars.This is introduced once and for all during manufacture.[/SIZE][/FONT]
  [*][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]The oil seal surrounding the piston rod in the upper body of the shock absorber has been especially designed with one lip to prevent the entry of dust and with a further two sealing lips to prevent oil escaping.The base of the seal is in the form of a circular strip which functions as a non-return valve.The flexibility of the strip allows the oil to flow back into the reserve tubes and keeps the gas pressure solely on the oil in the reserve. [/SIZE][/FONT][/SIZE][/FONT][/SIZE][/FONT]

[FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1][FONT=Verdana, Arial, Helvetica, sans-serif][SIZE=-1]The low pressure shock absorber design has enabled Monroe to solve certain problems associated with the MacPerson system.These shock absobers produce a very comfortable ride and very precise steering"[/SIZE][/FONT][/SIZE][/FONT][/SIZE][/FONT]

You dont happen to work for these people do you?

How very cynical of you:mooning::mooning:

No i just thought it mighthelp uke2:

Hi there TeeDee, did you change all four shocks, or just the front two?

Sounds like a very fair price if you had all four done.

Hi B.L.
Just the fronts boy
Just had a track rod end replaced and finally all the shake has disappeared
Removed/blanked the egr and boy what a difference,it is noticeable
Revs up to 4500 in each gear used to be 3700 when auto changed,really good,sounds smoother and a heck of a pong from the back end(discovery of course)
