I picked up an '03 Hardrock Pro Disc and took it down to the frame today.
Rear wheel out of true, left shifter not working and split cable housing are the knowns.
Get to the bottom bracket and its stuck.
Try all the usual tricks:
Soak in PB blaster
wrench in steel post and use frame to leverage it out
Nothing yet. Busted a tooth off the Park tool.
Time to get the 1/2" impact gun:
Wail away on it and the non drive side finally loosens up!
The drive side is worse. I had that impact on full for 30 seconds or more, then forward, reverse, it finally gives in after nearly hammering away the teeth on the BB. I used a 36" breaker bar to finish off the job!
Holy crap, worst BB ever. Now the threads look worn and not sure if cross threading was the cause, if t were crossed that bad it would have taken incredible force to get it in. Could that be the factory?
The threads feel "lower" than the leftover threads that were not in contact with the BB. Would a non-greased install and galvanic corrosion be the culprit?
I'm going to have the LBS chase the threads and hopefully that will clean it up enough to give it a long life when "cared for".
Any other suggestions?
Grease those threads people!!!
