CV axles problem

I have had a total of 3 different CV axles put in my truck with no success.

The boot on the drivers side tore and was flingin grease. I had already planned on having the gears changed and with 140,000 miles on the truck I decided to go ahead and change both CV axles while the differential was out any ways.

The new CV axle on the passenger side works great. However we are having a hard time with the drivers side.

The first set of new CV axles from NAPA would bind and not turn.
The second set were remanufactured CV axles from carquest. Same deal, they would bind while rotating.
The third set was a remanufactured CV axle from carquest.
The last resort is to use a Ford OEM CV axle.

I dont understand why the passenger side is any different than the drivers side. Anybody else had this problem? I'm hoping the FORD OEM CV axle will work but don't think it will work any different than the other axles we've tried.

The truck has the torsion bars tightened and my dad thinks this might be the problem. However the CV works correctly on the passenger side, and the old CV axles worked correctly also.

Could this problem be caused by bad ball joints or some other steering component being bad? I have no clue and really want to figure it out.

is there an adjustment cam on your lower A-arms where they connect to the frame? It sounds like you need to move the A-arm away from the frame.

There is a camber kit on the upper control arm, but not on the lower. This was put in when I went to have it aligned the first time after lifting.

They make a camber kit for the lower control arm? I'm guessing this will make the distance between the CV spans longer. How will this help?

I just noticed that the angle is not the same on both sides. The driver side is at a more severe angle than the passengers side. I'll get some pics taken in a little bit and post them up. The torsion bars are cranked the same amount on both sides and the truck rides level.

Is the angle different on other trucks? The same CV axle is sold for the right and left, but I'm starting to think that they should be different.

After a closer look it seems that they are at the same angle on both sides. I'll post the link to the pics I took anyways.
Passenger side



Drivers Side CV




One guy said that there maybe a problem with the hub on the drivers side. He said the axle should have about 1" clearance for the axle to move in and out in the boot. I dont think that there is any room for the axle to move in and out. The way the shop describe it to me is that the axles are bottoming out.

if thats the case, set the one you took out in the first place next to the replacement.

I guess I misunderstood your post, I was under the impression that the CV was being compressed between the hub and front axle. You've got a weird problem there, I'm with Klitch, lay the replacement and original side by side and see if there is a difference.
