I will be changing my rear bearing today and I need to buy a tool for the rotor retainer bolt. what size is the T socket wrench attachment?

 

T-50 torx

 

thanks texic. think i may go buy a set anyway. hate going out for 1 tool all the time.

 

You may want to buy 2 of them. I broke one when I changed my front rotors.

 

it went very smooth. at first i damned bmw for making all the bolt heads on the inside but ended with a golf clap when i found it was almost a breeze getting bolts out and back in.

but thats not the funny part. this morning i changed the driver side front and rear wheels after reading to much about cupping. took it for a drive and still heard noise in the back. after the bearing swap the noise was only in the front. yay! cupped tire and bad bearing.

guess i'll go for a balance and alignment tomorrow.

 

Put a little anti seize on the rotor bolt and they will never seize... will make for more life out of your T50

 

did and done. after 10 years you learn why proper maintenance is time saved. never mind why torque specs are important.

/done dosent always mean fixed.
