What/where's the knuckle? Noticed the same noise on mine tonight. Took a ride on a creeper underneath while my wife idled up the driveway (yeah, I trust her and it's coming from where the driveshaft exits the transmission. The rubber boot is dry rotting and squeeking at low rpms........ Is this a failed seal and what does it take to replace?

Thanks all for the help, it was the rear U-Joint, got underneath again and realized it was coming from the rear. Now that I have replaced both U-joints (single shaft) I'm parenoid I have a small vibraion from about 50-70 mph. It could very well be from my tires (toyo mt) and there from the git go but I have the "just did my own work jitters" and wonder if I didn't get it back together just right. My marks lined up on the front and rear. Someone asked in another post about where/how to have your driveshaft's balance checked but it never got answered. Anyone know how to check the balance or who can, thanks.
