Hello all! Hope this isn't an old questions that's been answered in the past. I just had the LN Engineering IMS bearing installed in my "03 Boxster. The old bearing looked good but I can sleep better at night now knowing it won't blow on me!! Anyway, my mechanic gave me the removal tools back. Is there a good reason to hold on to them or maybe try and sell it to someone else who can use it.
Any advice would be appreciated.
Good day...
