2003 pathfinder shake/wobble at 50+ mph

[03pathys]

Hey all, I have an 03 pathfinder 4x4(lifted 3 inches with 265/75/16s on it) with a lovely wobble going 50 or more, I think it may be a combo of things. I haven’t personally balanced the tires and I know a caliper is sticky up front. It was worse and at all speeds but I replaced the front cv axles and it now only shakes at 50+. 
Not a bad shake, but enough that I wonder what’s going on. 
Could a sticky caliper cause this? 
I’d love any input on what it could be, my first thought is tires probably need balanced.

thanks in advance

Sounds like a wheel balance issue to me. If this started suddenly, after driving in mud or deep snow, check that the back side of the rim is clear. A big wad of something stuck back there will make it shake like hell.

 

If you suspect the tires, visually inspect them (make sure they're round, no weird bulges), and if they are, rotate them (fronts to the rear, rears to the front). If it clears up, one of the wheels that was on the front may have thrown a weight. You could rotate one side at a time to work out which wheel has the problem.

 

I would expect a dragging brake to cause a pull, not a wobble. If the wobble is the same whether you're on the brakes or not, I would not assume it's related. That said, probably best to get the brakes working properly before chasing the wobble at highway speed.

 

While you're under there, check for anything obviously loose up front. Wheel bearings, control arm bushings, tie rods, ball joints, rack bushings, strut tops.
