Well, My Buddy Has A Mid 90's F 150 Flare Side 4x4 With A 6 Banger. Here's The Deal. There Is A Loud Squeaking Noise Coming From What Sounds To Be The Back Of The Tranny Were It Connects To The Drive Shaft. All U- Joints Are Brand New. Anybody Got Any Ideas Before The Trannt Gets Pulled, Thanks In Advance!!!

 

how new are the ujoints and were they neapco brand joints

 

have you looked at the slip joint on the driveshaft(if it has a 2 peice driveshaft)

 

they dont have 2 piece joints (mine doesnt) i dont think that varries engine to engine as i have a 302 and not the 300

check your u joints again, and make sure you didnt put them in dry cant tell you how many times ive seen that...

check wheel bearings, sounds carry weird sometimes, and you DONT wanan go through what i went through, TRUST ME

 

trans mount?

 

If its a stick shift maybe the throw out bearing is squeaking?

 

The Sqweeking Started After He Drove It 8 Hours Back From Ohio. We Thought It Was The U-joints, Replaced With Brand New From A-zone. They Were Well Coated With Wd Before Installed. Same Issue After They Were Put In. It Sounds Like Its Coming From The Tranny But I Guess It Could Be The Wheel Bearings. Easy Enough To Check. I'll Keep You All Posted. Thanks Again For The Help.

 

did you grease the nipples on the u-joints? I have done that before and it results in that same annoying little squeek....

good luck

 

you said ujoints but does it have a cv section?

 

Well It's Not The Tranny Brace, Still Holding Strong, Didn't Grease Nothin Just Hit With Wd, On The New Ones There Is No Zerks. What Do You Mean Cv Section????

 

He means a slip yoke with a carrier bearing like my driveshaft has:

 

no would be two ujoints back to back with a centering section

 

Doesn't Have A Centering Section, Solid All The Way Back.

 

They didn't offer true CV sections like that on these trucks. At the very most they'd have a 2 piece shaft like mine.

 

If they don't have a grease zerk the best way to put them in is to pull the caps and put some grease in them, then put the caps back on. WD-40 would eat up any grease that was in them to begin with and eventually wear away, run out, or dry out.
I would pull the u-joints out/apart and put some grease in them.
