Replaced bottom mounting but still getting some kick back n forwards when accelerating or de accelerating has anyone had this at 90000 miles two owners me and a doctor
Any comment re other mounts are they prone to go or not

Sounds like it could be the wishbone bushes. Easiest way I've found to check is look at the wheels when someone moves the car forward or brakes.

Could be the hydramount and/or tie bar to the OS inner wing - these support the weight of the engine on the driver's side. Have a look to see if the rubber as deteriorated on these mounts (the hydramount can be a bit hard to examine without actually removing it - it can look fine from the top, but when removed you may see splits or signs of the glycol fluid leaking out of it). Usually, if the hydramount or tie bar are worn, you get a more constant vibration into the cabin (felt through the steering wheel at tickover), rather than the 'kick' you are talking about (which is usually the bottom mount - are you sure you have the right mount for your engine ? - they are different between the petrol and diesels).

Sometimes, there is a knack to getting the engine to 'sit' on the mounts in the best position to avoid vibration or rocking - it involves loosening the two bolts that link the upper black bracket on the OS engine mount to the tie-bar at the OS inner wing, loosening the bolts on the lower mount, then pull the engine forwards using a flat bar placed between the round part of the tie-bar and the bracket over the hydramount - tighten the bolts on the tie-bar whilst holding the engine forward in this position. Then tighten the lower mount bolts. I found that doing this on my car made everything smoother/tighter, with less rocking/vibration.

Let us know how you get on.

Just noticed your car is diesel- the correct lower mount should have a T stamped on it, on the rubber part. If it does not have this , you may have a mount for the petrol cars, which are of softer rubber, and may cause some rocking when used on diesels.
