The brief
The Touran had gone choppy: a bouncy, floaty ride over bumps, the body pitching and rolling, and not feeling as planted as it used to. You never know what's lurking under a car until it's on the lift, and a check traced it to worn shock absorbers. He brought it in. The shock damps the spring, it stops the car carrying on bouncing after a bump and keeps the tyres pressed on the road through corners, over rough surfaces, and under braking. As the shocks wear the damping fades, so the body floats and rolls, the ride goes choppy, the car gets less stable, and the tyres skip along instead of staying planted. Shocks fade gradually so you get used to it, but it's a real comfort, grip and safety issue, so worn ones need changing.
The diagnosis
On the lift each shock got a bounce-and-inspect. The fronts and rears were past it, weak damping, weeping, the body carrying on after a push, and the front top mounts perished too. The shocks had all done their miles. When they've gone like that, you do them as axle sets with fresh top mounts, so it was the front pair and the rear pair, fresh shocks and mounts all round.
The work
Both front struts and both rear shocks were unbolted and removed, and new genuine VW-spec shocks fitted front and rear with fresh top mounts and bearings where needed, every fastener torqued to the manual figures. With everything back together the front geometry was checked and set so the new shocks weren't fighting a misaligned corner. A road test confirmed the ride had settled, no float, no roll, the car planted again over bumps and through corners.
The outcome
A composed, comfortable ride that settles in one motion, flat and stable through corners, and the tyres back to wearing evenly. The Touran went home riding properly again. Worn shocks only get softer and they take ride quality, handling, braking and tyre life down with them, so doing the lot as axle sets reset the car rather than chasing the next worn one a few months later.
