Car is vibrating

I need help bad. I replaced on the drivers side the wheel bearing and tie rod all motor mounts were changed to poly in the last month. The car still vibrates under acceleration only at 50+ mph. When not under throttle it is completely smooth. Under throttle it shakes pretty bad. I think it is a different problem but if I go around a corner and give it a little gas I can hear a loud rattling in the rear of the car. Please help me figure what is causing this. I am sick of replacing parts that don't need to be fixed.
 


the exhaust bouncing around maybe?

if its smooth at speed off the gas, then vibrates when on the gas the side you feel shaking has the bad axle.
 


are there some things i should replace while im in there? as i do believe the wheel bearing is just beginning to go out as well.
 
not really, unless you want to lca's and sway bar bushing and end links.

at least you dont have to take the brakes off this time round lol
 
hit and a miss guys replaced the passenger wheel bearing and cv axle. It did help a little but still vibrates is it a strut? i honestly have replaced anything i can logically think of that would make the car vibrate like this. it does also vibrate more when i hit a large bump or a low spot in the road.
 
That's weird. Did you torque the wheels to 100 ft lbs? How are the LCAs, inner & outer tie rods? Bent rim? Belt shift in the tire? maybe a wheel weight flew off

what do I check on LCA's, will look at the wheel weight but doubt it and what do I look for on inner and outer tie rods? no way it has a bent rim and it slowly got worse and how do I know if the belt shifted?
 
Look for worn bushings on the LCA and check balljoint. Jack up car safely and grab both inner tie rods and shake side to side to see if there is any play. Same with outer tie rods. Look at the tire to see if it is out of roundness to check for belt shift. easiest way is to dismount tire but you need a tire machine. youtube has videos
 
Here are the LCAs on my moms car, I would say these are bad. So I would look for possibly something like this. Mine looked similar before I replaced them. For shifted broken belts, on my car I pulled the wheels off and looked on them for any deformations and rolled them slowly and you could see the tread not flat it was raised up in some spots it also wobbled really bad.

nope they don't look anything close to that. So what would cause this only under acceleration... it makes no sense to me and i will be doing the coil packs, wires, and plugs so hopefully that fixes any other ideas guys and it feels like it mostly comes from the passenger front side. Anyone else got an idea?....
 


replaced the passenger side and the left side feels smooth when driving seems like the vibration is coming from the right...
