Ti Problems...

[first_bmw]

Hi all, need help...

Sometimes at Low speeds its like a mild thump thump thump, like creases
in the road.... then I rotated tires and it got better but I can still (sometimes) feel a thump, goes according to speed.

Also, when breaking I feel Vibration in the steering wheel...
like a jerking motion... any ideas, pads are 1/4 left.

ideas ?!?

if the thumping changed when you rotated your tires, its most likely a tire problem like a broken belt. it COULD be a bent wheel, but a thumpy tire is more common. as for the vibration in the steering wheel, its probably warped rotors. replace the pads and rotors and it should go away. i wouldnt recommend having the rotors turned since there isnt much material to begin with. and they are relatively inexpensive. worn ball joints or tie rod ends can make the virbrations worse, so check those out for play while the wheels are off. i had a ball joint fail on me and it was NOT fun!

now that i think of it, a thumpy tire like that can make a good deal of vibration in the steering. but since it only happens under braking and your pads are at 1/4, i'd say its the brakes.

I had similar symptoms rite after I bent m passenger side front wheel and I ended up having to replace the control arm on that side.
