One thing after another here. I had my front pinion seal replaced by a local shop and it is still leaking. Attempted to take it back and got into argument with the new owner and dont trust them anymore. Great shop for the past 10 yrs...now will not be returning. anyways, now I'm concerned with the pinion nut torque. Could an improperly torqued nut cause the leak or just the seal not done correctly? What are the symptoms of a too tight or too loose nut? I have not heard any whining sounds and can turn the front diff by hand when the tires are in the air. I know how important it is to have the proper torque set. Thanks everyone!!
