Took my Ford Escape to Metro Ford Service dept for diagnostics since the location was convenient. After charging $250 for diagnostics on an ABS light, rear differential leak, and possible power take off leak, they quoted me $2000 to replace the tone ring and the pinion and axle seals on the rear differential but advised there were no problems with the power takeoff.
After calling other mechanics for quotes for the suggested repairs, I ended up taking the Escape to a different mechanic recommended by a friend. The new mechanic advised that half the repairs suggested by Metro Ford didn't actually need to be fixed and that there was in fact a problem with the power takeoff that if I didn't get fixed was going to cause transmission problems! All in, the fixes came to only $600.
Don't take your care to Metro Ford unless you want to pay through the nose for substandard service and for repairs you don't actually need.
