Three problems related to suspension noise have been reported for the 1999 Ford Ranger. The most recently reported issues are listed below.
I was driving was about 20 mph and hit a small pot hole. I heard a loud pop bang noise and the left side of truck dropped about 2 or 3 inches. I thought the front end fell off. The frame is rusted so bad you can punch holes is the frame with a screw driver, the driver side torsion bar has collapsed due to rust on the frame that holds it in place, the crossmember to transmission is barley holding transmission up, the spare tire area is rusted in half, all main crossmembers are rusted in half and the frame is rusted in half behind fuel tank. Truck has 127k miles and the body body has little to no rust, upper and lower control arms are unsafe from rust. I do not understand how the body can be so good but frame and suspension is completely rusted to no return.
The frame at the right front suspension pocket rusted out. Upper control arm rear bracket is completely detached. Drove the truck to my destination with no issues, on the return trip it felt "floaty" as if it was out of alignment while I was driving down a town road. There was no bump or audible noise prior to or accompanying the issue. Body has very minimal rust, the rest of the frame appears solid. Truck has 104,660 miles.
