65 Squeaking from rt rear

[Brunomac]

Hello Everyone, Any idea's as to where this squeaking can be located at? I have attempted to take a video of the squeaking noise coming from the rt rear wheel of my 65 500. I only can hear it if I am rolling the vehicle without running the engine. I just cant hear it if driving. You may need to turn the sound up on the video. There is no play as that I can tell when trying to shake the wheel front and back while jacked up.
On another issue, if you look at some of my pics, I show what looks to be a cracked housing where the bolt holds the transmission (PG) to the trans mount, (may need to zoom in on a few pics to see). I would have never noticed this until I crawled under the car. It does seam to shake the vehicle a little when idling at stop lights not bad but seams a little rough. The noticeable shake goes away as the rpm's increase (at least it seams that way). Barely noticeable at this time, but it has raised a concern in me. I now see this cracked mount and am wondering if this may be the rattle or light shaking at stop lights issue? I also see I need to replace the strut rod bushings and am wondering if I have worn out that rt rear axle bearing do to the misalignment and twisting of the strut rods? Just an idea, any thoughts would be much appreciated. The left side or drivers side is quiet and spins somewhat freely, even though that inner strut rod bushing is absolutely shot. Pulling wheels, axles, brake drums, etc. and to un-assemble is above my pay grade and knowledge. Just trying to get a rough idea of the issue. I will be putting new wheels and tires on the vehicle along with a 4 wheel alignment, but I believe I will need to address the strut rod bushings and control arm bushing replacement before going for an alignment. The squeaking should also be addressed at this time, I am thinking either wheel or axle bearings. The issue with the compromised transmission mounting bolt hole, please share your ideas and remedies? I have reviewed the portals past write ups on some of the same issues but they were from an older time period and I am hoping some new remedies have surfaced. Thank you all in advance for your vast amount of knowledge, and your time trying to help a fellow Corvair lover. Ok sorry cant upload video so disregard helping on squeaking noise.

Bad u-joint is usually the cause of small squeaks. Of course it could be the stub axle (hub) bearings. Easy enough to check u-joints when having the strut rod bushings replaced.

On Powerglides I recommend using the nylon bushings on the inboard end of the rods and rubber on the outboard ends. Also, you need new bushings on the little "strut" rods, they are like shock absorber bushings, you can see them in your 3rd picture. Yes, this is done before alignment, or you are wasting money. I would spend money on these items before new wheels and tires. Or all at the same time.

That is not a broken transmission mount, it is a chuck of aluminum transmission case missing. Working so far, I am inclined to leave it be for now. Looks really clean under there, did you just wash it?

Add location to your right side information. I rarely see cars that clean here in the east.

If it is the axle stub bearings, then you can use Steve Goodman in Colorado to rebuild them (Rear Engine Specialists). Steve gave me good advice when I built my own fixture to fit the bearing spacers. Over the years I've come across some mangled and incorrect repairs that result in short bearing life and an even move expensive rebuild. The factory tolerances are too generous. Steve has found the sweet spot for clearances for maximum bearing life span and, as I learned, you must check the play WITH THE YOKE NUT TORQUED TO SPEC!! It is labor intensive to select the best shim size, but it will result in an axle that will last a long time.

Contrary to "opinions" you do not need to lubricate the rear LM wheel bearings after the unit is rebuilt. If rebuilt correctly, the axle will typically go for 80,000 miles - a long time for a hobby car.

Folks who had Steve G. rebuild the axle hubs all had positive comments.

Same basic axle hub design used on the 63-67 Corvettes and those folks tried add lube fittings and it was a disaster. Grease everywhere including the brakes!!! In fact NEVER fully pack an axle stub housing with grease - even the Shop Manual warns not to do that.

Yes to Steve!

Your strut rod bushings are clearly shot and there is metal to metal contact in the picture. Another possible source of a hard to find squeek is the park brake cable. Ithe inner cable moves slightly inside the outer housing as you drive and if dry it can squeek. Some penetrating oil on the outer cable casing will stop it for a while.

To all whom responded I thank you. All great direction and idea's. I will have further inspection performed when the rear strut rods are replaced. I am not going to touch that bolt on the transmission. I will still be trying to upload the 20 second video of me turning my rt rear wheel by hand and getting the annoying squeal. Which I can only hear when the car is off and if I am rolling it in neutral. At thigh speeds I cant hear it at all. My phone shoots an MP4 video and I don't think this portal likes it. I will try to get a link to the video set up. I really appreciate everyone's professionalism.
Oh, to answer Frank. The car is in southern California, I had recently purchased from an elderly gentleman's collection whom had all his vehicles stored indoors. I had not washed the underneath.

Remove the brake drum then turn the axle and see if the noise goes away. If it does the brake shoes could be adjusted too tight.

Thanks for the input I will perform that check once my replacement strut rods come in. While I have the car up in the air to replace the strut rods I will be checking u joints and the brakes for possible adjustment.

Rear brakes were the fix for the squeaking noise.
