I have a E38, 97 plate 4.4. Its done 111k with a full bmw

Resolved Question:

I have a E38, '97 plate 4.4. It's done 111k with a full bmw service history and runs great but, recently after pushing the car hard on the motorway for a few miles a couple of times, (I dont push it hard very often) the car developes a rocking motion , feels like side to side, when moving slowly or at idle. It shakes like this until I switch it off and leave it for a while and then it's back to normal!! Any suggetions?

where does the rocking motion come from? the engine? the body? somewhere else?

The engine.

thanks for confirming

 

this type of symptom would most likely be attributable to failing motor mounts. I would start here.

Not being machanically minded, can you describe what failing motor mounts are and what the fix would be if this is the case?

Need to know a little bit more and understand the problem identified and if there are any other possibilities.
Expert:  Steve replied 3 years ago.

motor mounts are just like their name suggests, they are what mounts the motor to the car. they support it and allow for some flex rather than a ridged, fixed mount.

 

the repair for failed motor mounts is to have them replaced.
