Cant put my 98 Hombre in gear.

There are 4 parts to this system. First is the clutch master cylinder, second is the slave cylinder, third is the clutch throwout bearing, and last is the clutch pressure plate. These are all the parts that can be the issue. The master cylinder is the part that pumps the fluid to the slave cylinder, which pushes on the linkage to the throwout bearing, which pushes on the fingers on the clutch pressure plate, releasing the clutch. If you drained the fluid out, first you need to make sure that all the AIR is out of the system. It's just like brakes, it will not pump if it has air in it. The hydraulic portion of the system rarely gives problems, so here's a question. How old is the clutch in your truck? If it's over 100,000 mi, then you should start suspecting the throwout bearing. Did the truck make any groaning noises when you pressed the clutch recently, and then perhaps it stopped on its own? These are signs of throwout bearings going out. Here's the bit of troubleshooting that you need. go under your truck, and find where the slave cylinder attaches and pushes on the linkage that goes into the bell housing on the transmission. Feel this linkage; it should have very limited to no movement. if it moves significantly, then your throwout bearing went out, and you will need to replace your clutch and throwout bearing. If not, then it's the hydraulic portion of the brakes, and you'll have to troubleshoot between air in the system, master cylinder failure, or slave cylinder failure.
