custom driveshaft

[thebison]

hey all, im swapping in my 8.8 this weekend, im going to need the bigger u joint flanges as my trucks an 88, so while in the process im going to cut the exlplorer driveshaft and my existing one to make one solid drive shaft for the rear, im going to try and balance it myself as there is no driveline place nor do i want to spend the money? is this a bad idea? do i have to put it on a lathe to get it perfectly balanced?

Really getting the thing straight will be more important than balance. I've made a few driveshafts with zero problems and only one had vibration only due to a bad slip yoke. If you get it straight you will have little problems with vibration. Personally I have had my driveshafts up to 140mph with no problem at all. To balance a shaft you are going to need a lathe of sort that will allow the shaft to spin freely to find the heavy spot. From there you will need to find a way to weigh that imbalance or guess with weight to get the shaft neutral.
