Any issues running 1 degree shims + axle shim for extra lift?

I'm currently on the TRD lift with 1 inch block. THere is a slight vibration/humming noise and considering adding in a 1 degree shim to see if it fixes the issue. Also, the rear driver's side lean is .75 lower than the other side so I was thinking of adding a 1/2 inch axle shim to even it out. Any issues with this setup?

1/2 axle shim

 

Yes and yes. I would measure when the gas tank is full and then when its empty to get a more accurate difference in height first.

You could even go with 1-2 degrees of an axle shim. Some of the tacomas out there came from the factory with a small axle shim.

Then you could try a carrier bearing drop. But really what you should do is watch a few utube vids on how to measure the axle angles to see what it looks like as well.

I would also examine your tires. Are they worn, have they been recently rebalanced?

Have the U-bolts been re-torqued?

Not in any particular order for any of it.

 

Thanks, im gonna take more measurements. Im wondering if maybe the ground isnt flat which may cause differences. Tires have 7K miles, they are the original.
