time to replace or not?

My truck has some transmission issues. I'm trying to save some money. I want to know if 30-40 % of clutch life left is enough life left to operate the truck weekly.

Thanks in advance.


ID say its rather "penny wise and pound foolish" to not replace the WORN Clutch disc ,if the transmissions out and you've found the clutch disc significantly worn, it takes a couple hours and a decent amount of effort to replace a clutch disc, a clutch disc by it self is one of the least expensive components that , like the throw-out bearing should be replaced, any time it appears to be worn or in my opinion any time the transmission is removed If theres at least 40K miles or more on those components, in a normal transportation car/truck, and keep in mind that if its replaced before it wears enough for the rivets to contact the two clamping surfaces to prevent damage too the pressure plate and or flywheel surface, its much cheaper to do it.
obviously the QUALITY of the parts you use and the CONDITION of the parts your needing to replace all effect the cost of the clutch rebuild or replacement, and catching the clutch wear before the flywheel or pressure plate needs to be resurfaced or replaced is a key factor in reducing the expense.
its costs a good deal more to resurface a flywheel and rebuild or replace a clutch pressure plate once the components get damaged by an excessively work clutch disc

its a good idea to
post your city and state in your profile,
when you register on many auto web sites

, theres a very good chance that some experienced local guy would like to help you out, too save you some money and still make some money himself.
$500 for a clutch replacement is fairly cheap from most dealerships but you could do the work yourself for under $200 and certainly I know if you were local to me Id help you replace the worn disc,and throw out bearing for significantly less than the dealer price, and I'm sure that I'm not the only guy willing to help out some young guy while saving him money, teaching him new skills and making a few buck$ along the way!
