Trek Isuzu mechanic -- Excellent
There is an expert Isuzu mechanic in North Phoenix Arizona, that can fix any problem with chassis on the older Treks built on the Isuzu frame.
His name is Kim Nanni and can be reached here:
He now has a mobile repair truck and can come to you within some distance, but you'll have to call him to find out how far.
So far, he:
Made my brakes work very evenly and stop straight,
Repaired my parking brake,
Replaced a broken bolt on the exhaust manifold,
Balanced the driveline,
and of course all maintenance.
He can also rebuild transmissions, and even swap your engine with a more powerful one.
