Question about 1991 GMC Sierra
I recently had the fuel pump, fuel regulator and the fuel line replaced by a shop. Now, when I reach speeds of 55 mph, the truck begins to shake rather violently. It only lasts for a couple of seconds and will happen again and again as I accelerate beyond 55 mph. It seems to be ON the engine, not IN the engine, if this helps any. Other than this, the truck will operate great throughout acceleration and at a constant rate of speed, as long as I stay under 50 - 55 mph.
Crankshaft balacer going bad,can cause the crank to break if left unchecked
