Ok all, I have a '86 chevy 4x4 and I think the front passenger u-joint is starting to go (makes a wa-wa sound when I turn). I have replaced ones for the rear and front drive shaft before but not on the front wheels. About how different is it to do by comparison from the drive shaft u-joints? Also I have a canoe trip this weekend and need to take the truck for all the gear. The canoe trip is about a 3 hour drive each way. Do you think it would be alright? What's the worst that can happen if I take it? I would like to of had it done before the trip but work and working on the wife's car took priority. Sorry if this is a stupid question, I am more of a motor guy than a suspension guy. The u-joints are all stock except for the ones on the drive shafts I have replaced. So I cant complain, it's a great truck! But any advice would be nice!
