65 riviera carrier bearing, a vibration, and a squeal...

Dented driveshaft? Wheels out of balance?

 

broken tire belt?

 

Harmonic Balancer? Could be cracked or chipped. Seen it before.

 

The carrier bearing should have some adjustment, slide back and look uo the drive shaft, the front shaft should be running straight back from the tranny. That will cure your squeel, make sure that the slip joint on hte rear shaft is full of grease, they get dried out and get slop in them that may cure your vibration. Also make sure that you don't have a dry U-joint or velocity joint.
Or take a day or two off and come see me, I'll find your vibration and squeel. Might be pretty cool to see you hauling that bugger behind the coupe as well.

 

I've seen a bent yolk before too in a TH400 application

 

Just from what I recall on my old X frame Chevies, it was important to
have weight on the back axle (ride height) before tightening the carrier
bearing bolts...

 

If if were the motor, bring the rpm's up while parked. No vib? Drivetrain. Have the shaft check out/rebalanced by a pro. Just as a process of elimination, and piece of mind. Did you have a load on the rear tires as you tightened the carrier mounting bolts?

 

How's the trans mount?

 

Ryan, I've had issues with vibration in my Riv. It's probably a u-joint. Hell there are only 5 to replace. I had to replace the rear u-joint in mine. And keep them all greased up. I still feel something on occasion. But nobody else does. Maybe I'm paranoid. Take a look around on this site. http://forums.aaca.org/f177/

 

Did you get the front and rear driveshafts indexed properly? All ujoints have to be aligned the same (learned this the hard way with a '72 Chevy truck).

 

Probably would account for the vibration, you could be getting a harmonic that is passing through your engine or chassis.

Here is one for you, the ravens roadster had a death wobble. When we pulled his 305 and put my ballanced engine in it the death wobble went away. Harmonics can wreck havock on about anything.

 

I got on in the basement if you don't have any luck.

 

this is how I ended up finding one for my new yorker. looked at the dimensions and found the closest thing. the one that everyones computer said was for my car wouldn't fit.

they list sizes and dimensions. may be better than trying to find the correct one for your car..

Ryan: You are dang luckly that fan clutch didn't go have lunch on your radiator,it was heading that way.

 

If after you fix the fan and the vibration comes back, 9 times out of 10 its a tire.

 

I've had a bad fan clutch cause a vibration that felt like a driveline vibration before. I also chased it for a while and it surprised the hell out of me when I figured it out....

No shit!

X3!!!

Good bit of troubleshooting to find it, when you were so focused on the bearing and u-joints!

I would still be under there counting needle bearings!

 

Driveshaft.
Since I got screwed on the earlier prediction, what do I win?

 

If a clutch fan fails like that would it send a blade through the hood or is that just the fixed blade fans? Cuz I have seen the fixed blade fans shoot right through a hood on a 50 chevy...

 

When my water pump let go on the way to last years HAMB drags it vibrated the whole car. I honestly knew I had a bad cv or support bearing so I thought that was my vibration. Changed the water pump the vibe got a lot better. Changed all the u joints,bearings and cvs this year and got better still! I do still have the Riviera rattle though I think it is the fuel return line. One more thing, just curious does yours seep heat around the steering column?

That could easily have been all your problems. But you found IT before IT found you. When you lost the vibration for a while, the fan just took a set where it didn't vibrate for a spell.

Hey ,you found it before the dreaded wham bam followed by the sweet hot
smell of antifreeze... I call that, "Winning"...

 

Been there on a few of these issues with my '64 Electra.
Sorry to be chiming in late but here's 2 things.
That carrier bearing should be locked down while the suspension is loaded with wheels on the ground. And..
If you're feeling that clutch fan vibration, you should check your motor mounts too.
Put the car in drive and with your foot on the brake rev it a little and see if your motor lifts up on the right side. This style mount becomes separated and transfers a whole lot of vibrations.
Good luck,
Steve

 

+1 And or worse. I've fixed the aftermath of a couple of those that came apart running down the road and it wasn't pretty. Lucky for me I got paid to work on them and they weren't mine.
