Hi guys I dont have much experience on posting threads , so sorry if I'm not doing something right and please tell if there's a better way of asking a question like this.
I've searched on line and spoke to people around but couldn't find a good answer.
I have a 2008 bmw 535xi. Recently I've replaced serpentine beltand tensioner. When started the car I looked very closely on how the belt runs and noticed a little wobble on the new tensioner I installed. The wobble is little and I can't catch it with camera, nevertheless it's there. I had the seller send me a different tensioner same brand tho ( INA) same problem. I understand there should be 0 wobble on any belt accessories. Am I wrong? Is a little wobble acceptable?

its gonna have some 'wobble'. is it make any abnormal noise?

 

No noise, actually the old one was making noise. Now the belt runs very quiet, but everytime I look at it I just see that wobble and drives me crazy lol. Thank you very much for the reply, makes me feel a bit better but will continue to watch it and do more research:-)

 

Hmmm. I don't think I would describe anything to do with the tensioner as having some wobble. I will be under the hood this afternoon and will take a look at mine. It is pretty new with hardly any miles on it.

 

Agreed. I replaced mine less than a month ago and there is no visual wobble to me.
