When you get it up in the air. Check all four tires for runout.
Professional method is to run a dial indicator against the middle of the tread and rotate it 360 deg. Anymore than 0.040" you will feel. Shaking pedals etc, that will be over 0.10".

Driveway method. Spin the tires. Fronts by hand, rears with engine idling in 1st gear. Place something really close to the tread. Last time I did this I used an empty antifreeze jug. If you see the space between the jug and the tread stay consistent, you're good. If it's going far/close/far/close. No good.

Vibration:
I looked at the axles I do not think they are bent. I am pretty sure I have a wheel bearing gone though. If I have the drums off should there be any play in the axle I have play in and out and up and down but its not real extreme. Should there be any play?

The squeaking/chirping:
It squeaks when clutch is let out and until the rpms get up a bit in 1st
It does not chirp with the clutch out and car in neutral
It sounds like it is coming from the back of the car not shifter so I am really unsure
It does it going forward or backing up
Does anyone know what it could be or something for me to check?
Thank you, all

Please does anyone have a idea? I cannot afford to bring this thing to a garage.

Movement in 'n out I think is normal up to as much as a 1/4in? That up and down(not sure),but doesn't sound right.If I was in your shoes I would try to save up around 1300bux+and get a complete frrp rear end rather sinking money in now and or a gear swap later. Just some thoughts

It sounds like a U-joint may be dried up and it squeaking now. And since the joints dry now, it'll catch bad and could cause the vibration. Tae the driveshaft off and check the U-joints thoroughly. Just checking them while the car is in the air isn't enough.

I have seen grease nipples on the u joints is it okay to grease them to see if the noise goes away. I read somewhere that they are not supposed to be greased

I just realized that shouldn't it squeak all the time just not under load if it is the u joints? The noise does stop when the clutch disengages.
