Default Rear vibrating on acceleration.

I was wondering if anyone can help me here with a situation I have that's causing me to go nuts.
On acceleration the rear driver side vibrates. When I let go of the gas it goes away. If I accelerate and corner right (putting pressure on the driver side) it also goes away.

I recently did a axle nut TSB on that side because it became very loose. The clicking noise stopped but now I have this vibration.

Yes it's been lowered on springs for the past 2 years.
I've been doing searches on these forums and I found a thread where people are getting the "shakes" after their axle nut TSB... what can this be?

Are my CV joints worn because the car was lowered without axle spacers?
Can it be my hub bearing?

get spacers, if it still vibrates then your cv joints are worn

check your cv joint cups first and swap if neccessary before you buy spacers

Lowering is not the problem.

Your inner CV joint cups are pitted. switch the cups (drive buckets) from left to right and it will be good as new. Dont bother with spacers.

Cost: $0.00

Amount of cars I have lowered, all mileages: around 30

Amount of cars that got a vibration after lowering: 0

Lowering the car MIGHT start a vibration in a car in which the bucket has already started to pit. It moves the bearing to the soft part of the pit, or the edge. It allows it to chip and accelerate the pitting.

But LOWERING is not the problem. I still believe spacers are a complete gimmick.

If it vibrates on acceleration, and immediately stops on decel, then yes its pitted CV buckets.

My axles have been vibrating for about 2 years now and 40k miles and simply ignored it until last week. Now the car makes a pounding and greatly amplified vibration when on the gas. Turning left is simply impossible while on the gas because the vibration is so violent it rattles the mirrors. for car neglect.
