So I have some creaking coming from my passenger side top mount I think. Had a good inspection under the car and everything looks fine so I'm putting it down to the TMs. Going up north on Monday. Geo is out ATM and ideally want it set up before I drive 4hours+. Won't have any time to get the top mounts replaced before then. Obviously when I get the topmounts replaced I'll need the geo set up again. But my Q is will having worn TMs cause any adverse affects to handling and what's the downsides apart from creaking from front end. Also when I do get them replaced will I just need bearings or upper Mounta too?
