1998 Ranger 4 cylinder 5 speed, 186000 miles. Drive train backlash or timing belt?
Pulls fine up the hills, but just as it tops the hill and is not under load, and begins to coast, I feel an irregular backlash, before it starts coasting against the engine. I can't find any lost motion in the U joints. Wonder if it could be in the clutch disk? Or is the timing belt suspect for making the engine run irregular under no load?
Possibly an issue in the rear end. Might try jacking both back wheels off the ground(properly supported of course) and with truck in gear roll your rear wheels over forward and then backward. Feel anything that might resemble what you are describing? Hear any unusual noises? Just a thought.
Oh and watch wheel movement with driveshaft movement. Forward and backward. Is there a lot of play in it when you change directions?
