That thread, and sorry to post the other site onhere, i hate that site, but thaty thread is pertient to my problem-
Ok, so for the past 2-3k there has been this wierd scratching noise that has been getting progressively worse, under any kind of load it is very very noticable, let off of the fuel, and it goes away, but as your coming to a stop, when the transmission slows down to engine rpm, the scratching commences again, totally stops when sitting still.
Engine off, in drive, rolling 35 mph, noise is present to a degree, but not bad.
engine off in neautral noise is less present, but still there.
engine off, transfer case in neautral, and transmission in neautral, naturally, no noise...
So, yesterday, i go up under the truck, grab the shaft, i have 3/4" to 1" up and down movement on the center bearing (beside the fuel tank) and about 1/8th- 1/4 turn counter and clockwise movement in the shaft, audible click in rear end and in the transfer case. I am relatively sure the up and down play is not acceptable, but what about the rotation? i can tell where the t case has leaked a little, or appears to have. I had originally thought that this noise was attributed to bad bearings in the front wheels, and really didnt worry about it, as i had planned on replacing the brakes in a couple months.
then i find all of this loose slop down in the shaft. makes a guy worry, ya know? this isn't gonna be cheap (the rotation slop)
truck has had an extremely loud CLUNK-BANG, for approximately 60,000 miles, in the 40-45 mph range,(ford says normal!) when you let off and get back on it, i am assuming the rotational slop has been there this entire time, and is nothing new. the U-joints are not where the slop is coming from, they may could use some grease however. If i can find my grease gun in the shop, i am going to go hit every ZERK i can find. (i know, it's overdue)
Thanks for time, and suggestions, Brian
