Collar and Hub Wear

(1/1)

september2017:
Q:   John Twist - Congratulations on your retirement. I want to thank you for your informative videos. I purchased my 1977 MGB a year ago. I live in Madison, Mississippi. Their is only a handful of MGB's in this area. I really can't find any shops here that work on them. Can you please take a look at the pictures and let me know if this is normal wear on the collar and hub? The oil seal was leaking and upon taking it apart, I found some wear on the parts. Thanks again and have a great day.

A:   The wear on the collar is normal -- that is, where it meets the rear hub oil seal.  You can polish the collar with very fine sandpaper or cloth.  Be sure to lubricate the new seal with a lot of grease when reassembling.  Otherwise it will run dry for a while. 
The wear you're concerned about on the tapered section of the cone and on the inner hub are of zero concern.  These two surfaces aremated very tightly when that rear 1 5/16" nut is tight.  Nothing turns or wobbles on those surfaces. 
Hope this helps!
John Twist
SAFETY FAST!
