I have a 99.5 CC SD DRW 4WD 7.3 ltr 6spd. Is there a grease zert(?) for the clutch/pressure plate throwout bearing, if so where? Never seen one before. Also, how much can I increase my tire size on this truck (using stock 16" wheels and not putting in lift kit) and not have steers rub when turning (realizing I'll need to put spacers between the duals)? Thanks for any help, Luke

 

I don't know about the throwout bearing but it should be greasable if it isn't. The tires can't be any larger than 285 75 16. This is a 33" tire and the widest for those rims.
