After 121,000+ miles and letting the wife try to drive it a few times my clutch is starting to silp. I have a 98 f150 with a 4.6 5 speed with a tow package. i was pulling a 68 coronet on a trailer comming up a steep hill had it in second gear going 25 mph and about half way up i started smelling the clutch burning. After i got to the top the smell went away and havent smelled it sence. So my qustion is what clutch throwout bearring ect do people like the best for mostly every day driving and part time offroading and pulling?
