Again, thanks! | | | | Joined: Feb 2006 Posts: 1,867 Shop Shark | | Shop Shark Joined: Feb 2006 Posts: 1,867 | I was drivin the 53 (3 spd, 216) around today and theres a weird noise coming out from under her. It kinda sounds like 2 pieces of sheetmetal perpindicular to each other screeching against each other.
I crawled underneath it, cant find anything loose. Shes done it in the past and it hasnt effected the drive but Ive never known a screeching to be a good thing? Kinda sounds like it coming from the rear.
No growling, howling, ticking or anything else. Any ideas???

My problem was front wheel bearings. I would suggest inspecting your wheel bearings.

Loose baffles in the muffler? They say money can't buy happiness. It can buy old Chevy trucks though.

The mufflers rusted out on the inside so Im pretty sure its not the baffles. The Ujoints dont have that characteristic clunky noise when going from a stop to accel or accel to stopping fast. It also doesnt do it all the time. It almost seems like it does it more when stopped then accelerating and turning, or when upshifting into 2nd while not quite going fast enough. ???

Sound can travel and what/where you think you hear may not be the case. Back in the '60s I worked at a dealer who employed a fellow full time to work only squeeks, rattles, wind noise and water leaks. It was amazing how he had the knack for tracking these things down. I remember seeing him hanging out of a car door with his head almost hitting the street trying to locate a sound underneath. Often a customer would complain of a noise "in the dash" that was actually originating somewhere else in the car.

Good idea, although the wife is a little scared to learn the 3 on the tree. I guess its time. Bruce K, I checked, and yes my nuts are just fine. I was still hoping someone else had experienced something similar... Thanks, Jeff | | | | | Joined: Mar 2003 Posts: 181 Shop Shark | | Shop Shark Joined: Mar 2003 Posts: 181 | Check body mounts. I had to fix a guys F word when the radiator support rotted out at the body mounts. Caused the cab to flex off the frame giving it a sheet metal scraping sound. Only did it going over uneven ground. | | | | | Joined: Apr 2004 Posts: 703 Shop Shark | | Shop Shark Joined: Apr 2004 Posts: 703 | While you're under there, check the bed mounts. I had a similiar noise I tracked back to being a loose bed mount.
It allowed the bed to tweak and squeak in certain situations. | | | | | Joined: Dec 2002 Posts: 3,441 Moderator - The Electrical Bay | | Moderator - The Electrical Bay Joined: Dec 2002 Posts: 3,441 | are your brake backings bent into the drum a bit?

Mine made some noises I might have described the same way as it failed. It quickly got worse.
Hey I'm headed out of town, but you could invite bigmacdaddy over to ride on the back or underneath to listen while you drive it trying to make the noise.

Could it be suspension? I had an elusive noise which ended up being the shackle bolts/bushings.

No problem at high speeds. | | | | | Joined: Jul 2005 Posts: 1,158 Shop Shark | | Shop Shark Joined: Jul 2005 Posts: 1,158 | My clutch pedal screeches when it gets used. The pedal is rubbing on the toeboard because my cab mounts are less than ideal.
How are your cab mounts? | | | | | Joined: Feb 2006 Posts: 1,867 Shop Shark | | Shop Shark Joined: Feb 2006 Posts: 1,867 | So after tearing apart the tranny and rear end, The pinion bearing is the winner!
Totally and completly shredded to pieces, it only has about 8 ball bearings left. I guess i should be happy it lasted a good 54 years now...
I guess its time to order that 3.55 set of gears and enjoy going more then 50 mph. Darn I have to order more parts.
