Is a Damaged Spindle Safe to Use If Hub Fits It


This spindle had a bearing blow out and something rubbed into the spindle causing the permanent indentations by the threads, the new hub slides on and secured, is this ok?


Expert Reply:

It might seem that the spindle being slightly bent isn't a big deal but it can definitely lead to another blowout so you'll want to replace that spindle with a new one. It looks like you have a straight spindle like the standard BT8 found as part # TRU94FR for a circular end or part # TRU97FR for a square end.

A damaged spindle will cause more friction which, in turn, increases the amount of heat produced which can lead to your bearings failing or a tire blowout. So any time a spindle gets damaged - even if it's just a nick, you'll want to exchange it to avoid any emergency stops along the road.

Attached are some videos for you to check out. If you have a different spindle size please let me know and I can help you find the correct replacement.
