98 ranger 4wd issues
New to 4wd, any help would be greatly appreciated. Thanks in advance!
I recently purchased a used 1998 Ford Ranger XLT 4wd and I'm having some issues with the 4wd system. Forgive me if I don't use the proper terminology, this is my first 4wd and I know next to nothing about it.
98 Ranger XLT SuperCab
5 Speed Manual
When I engage 4wd high and begin to move forward there is a substantial clinking or chunking sound which increases in frequency as the speed increases. I assume something is stripped somewhere or not fully engaging? Also, I assumed up until today that 4wd low was working properly, however I tried to back up a steep gravel hill in 4wd low and after a few feet the rear tires just seemed to jump up and down quickly and I ended up going nowhere. Conversely, while going forward in 4wd high everything seems to have engaged properly, I assume this because it is somewhat difficult to control the steering, the power seems to be there as far as I can tell and the speed is lacking which leads me to believe that it is engaging properly at least in forward motion.
Where should I begin troubleshooting first? Are the hubs just worn, and if so how difficult are they to replace?
