I had OME shocks and coils installed just over two years ago (heavy duty all round). Had no problems with them at all.
Also got Cooper STT's a year ago (265/75/16), very happy with them.
Recently my Pajero started bouncing on uneven tar roads. At highway speed 120 - 130 especially with a sidewind the Pajero rocks from side to side and feels unsafe.
Took it to TWT - salesman said flat spots on the tyres caused the vehicle to lift ??
Got a second opinion from Johan at First Alignment (who originally fitted the suspension)- he took the car for a test drive. Commented that handling and going over speed bumps felt fine. However when he felt the instability at speed he said I should replace all 4 shocks

Any ideas ? Shocks are just out of the 2 year guarantee, cost me a little fortune and I expected a longed life out of them. Could the problem be that I fitted heavy duty without really carrying heavy loads? I did a few Gr 2-3 tracks and occasionally drove sand. Visited Atlantis twice. Nothing major in my mind ?
Any advice as to what I should do ?
