I've just rebuilt the front prop shaft on my 2004 TD5 Auto at 190000km

The suspension is in standard configuration. On a trailing throttle at about 60 kph I could just hear a slight chirping sound, while I couldn't feel any movement one of the UJ's was hot to touch after a short run. On stripping it down one cup was completely dry.

The universals came out without too much trouble, but I was having trouble with the ball joint as most methods apply an uneven extraction force (I'd read all I could find in the various forums)

After removing the small oil seal, all the rollers and the small cup at the bottom, I noticed a small lip at the bottom of the hole. I then machined the small device pictured with a main body diameter of 13mm, lip 15mm, length 20mm, and a 8mm threaded hole through the middle.

The device was inserted into the ball, and the ball rotated 180 deg, a long threaded bolt then allowed the ball to be easily extracted.

One point I didn't see mentioned anywhere is that when assembling the universal both legs need to be inserted into the cross before the cups are inserted.

I used Hardy Spicer K5-A757 universal Joints and a SCV-82B ball, which I think were the best I could find.

I also couldn't get my grease gun onto the supplied grease nipples as it hit the sides of the cups before it was fully locked in. I eventually found an extended 1/4 inch threaded grease nipple that I used for greasing before reinstall the original nipples.

I considered getting a Tom Woods replacement drive shaft but there weren't any available in Australia and the US$399 plus US$230 freight put me off.

Did something similar with a m8 coach bolt head wedged with small chisel:)

I just took mine around to a mates place he tapped it with a welding electrode and it came out. He did something I didn't see, but came out easy after that

Doing this atm. The ball came out easily, the race it was in was a fair bit harder and had to use a dremel tool. Hoping to finish on next break.

I'm about to rebuild my prop shaft. Hardy Spicer have the centre ball kit but they noted that the SCV-082B is not an exact replacement and some machining is required. I haven't seen this mentioned in any threads. I presume others have been able to press the new one in ok?

thanks
