Saturday was the day that we conquered the dreaded gear growl in our Humber. Another set of Humber ears came down from Stawell bringing a second transmission. A drive of the old girl and a diagnosis of transmission noise was confirmed, so, out came the transmission for the 3rd time and in went the donor transmission; road test and you guessed it same noise at the same speed. Heart breaking to say the least, so off came the front drive flanges to discount the front drive line and noise was still there. Could not believe it
some serious head scratching then it struck us; the clouds opened up, angels began singing and their it was staring at us. The tail shaft from the transmission to the transfer case was out of sync by 90%
Removed the shaft split the slip joint, realigned, refitted and now I have a very, very quite vehicle. Somehow in a past life the tail shaft must have been reassembled incorrectly and I did not pick it up, with the rear diff solidly mounted the tail shaft was winding up and trying to turn the gears against themselves. This explains why the transfer case and transmission both had noise and when I hit a bump the noise stopped as this allowed the tail shaft to unwind and de torque.
Anyway a couple of shots of the transmission being removed again and the donor vehicle going to the Humber grave yard at Stawell.
A very happy Humber owner at the moment.
Cheers,
Dave.
