So there was a bunch of play in the stock front driveshaft on the Jeep. It needed to be replaced. Being that it was an ‘81 with the 4-speed tranny, there were only two years that they used that size front driveshaft: ‘80 and ‘81, consequently the years with the lowest number of Jeeps sold due to several reports and articles overstating the rollover probability of the Jeep CJ. Two months of trying to find a used driveshaft were fruitless. I was forced to buy new. With the Cdn dollar still around par with the USD, I started looking south. What I found was that having a custom, stronger driveshaft built was around 10% cheaper than buying a stock replacement. After reading around a bunch, I decided on a Tom Woods custom shaft which came with a pair of their really great Gold Seal U-joints.
Here it is beside the stocker:

One of the differences I noticed about the two was the amount of weight needed to balance the shafts. The Tom Woods shaft has a total of three quarter-sized pieces of metal welded on while the stocker has a large chunk of 1/4″ steel welded on.:

The new shaft has just over 2-1/2″ usable travel. More than I’m going to need.:

Going to a 2″ shaft did require a bit of trimming on the skid-plate – scratch one jigsaw blade! The install went quick and easy. Even for this non-mechanic computer geek. Found out that the best combination for removing grease and grime from my hands was liquid tide and one of those soapy SOS pads. I kinda like having clean hands when handling my 2 month old daughter!
Some installed pics- at the front diff:

I have to believe that this is the strongest part of the Jeep now.
After the install, I took the Jeep up Mt. Prevost until I got stuck in the snow (all terrain tires – bah!) and the shaft was sounding good. On the way back down the mountain, there were some really bad sounding crunchy, grinding squeaks coming from the front end. Seemed to happen most when turning. I managed to have a look when everything was at just the right angle for the problem to present itself. a broken U-Joint on the passenger side of the front axle! And I’ve been driving it like this! when not under load and the wheels are straight, it looks normal enough to hide itself from a local auto shop with a “golden touch”, but here’s what I saw:

Crap. There goes the rest of my budget.
