4x4 clunk/jerk; fine in 2-wheel drive 2000 ranger
I have a 2000 ford ranger 5-speed manual that has a problem with the 4-wheel drive. It's an automatic dashboard push-button. One shop and one transmission shop in town have already taken a stab at it. After looking into everything they could think of, replacing the automatic motor (for the 4-wheel drive), rebuilding the transfer case, working on both front/rear differentials, they have given me my money back, as the problem is still there. The truck "grinds and pops/jerks" when driven in 4-wheel drive (apparently tearing up the transfer case, as it was a mess)....and when in 4-wheel drive, if you turn ever so slightly it is like you have the brakes on (something locks up big time). There's also a slight whistle coming from the transfer case when in 4-wheel drive. It does shift into 4-wheel drive though. Someone thought it sounded like the gearings didn't match, but that can't be the case as the truck has never been worked on other than oil changes/fluids, etc. The problem began over time last year, gradually getting worse to the point where we just stopped putting it into 4-wheel drive. However, we'd love to get it fixed! My original thought was to just get rid of the auto-lock hubs and put on manuals, as we thought it was just grime build-up causing the hubs to not engage....it is bigger than this, however. I put new tires on it, as one shop thought one tire might be ever so slightly more worn than the others (very minimally so), but that didn't change anything.
anyone have any inklings? planning to take it to another shop at some point....
