BMW 328 1998 heavily shakes sometime when on high way, what could be the problem?

It shakes as if something is going to fall apart. It looks very dangerous. Showed to the mechanic and he says nothing is wrong with it. Any one has any such problem or any ideas? It has new tires which were replaced to correctly the problem but did not do much. The shakes appears on high speeds lets say once in 50 miles drive. It also wobbles at +60mph not all the time though.Any ideas will be appreciated. The car is otherwise in fine running condition.BMW 328 1998 heavily shakes sometime when on high way, what could be the problem?Take it to a different mechanic!

There are a myriad of possibilities:



Bent wheels

Blown shock absorber(s)

Failed suspension bushing(s)

Ball joint failure

Broken rear differential mount

etc, etc.



It's also possible that your new tyres were not balanced properly, or one has a defect, such as a slipped internal belt.



Long story short, get it to a competent mechanic; there are too many potential causes for specific diagnosis without seeing and/or driving the car.BMW 328 1998 heavily shakes sometime when on high way, what could be the problem?

This could be a number of things, but one thing for sure, ITS NOT NOTHING!!!!!!.........



If you front wheels are not balanced or need aligning, this will cause the car to 'wobble' but you would feels this more via the steering wheel.

It could also be the wish bone bushes as when these start to perish, they don't support the suspension arm which also keeps the wheels Parallel.BMW 328 1998 heavily shakes sometime when on high way, what could be the problem?I read your question afew days back with nothing to add, but I just had a thought. it is a intermitten problem not being constant. have your calipers checked, a sticking caliper on one wheel could give reaction that your are feeling. it is easy to test the theory too, drive the car on the highway and tapthe brakes. or keep this in mind and see if the wobbles/shakes start right after you touch the brake.
