I could have been clearer. The steering knuckle moves as well as the rotor and caliper. The outer CV moves along with it. If the bearing was bad the outer CV would move also.

I would also look to see that the front differential has the correct amount of fluid in it, as when an axle is pulled, fluid always seeps out.



If it is the outer CV joint that is moving in and out, you can just buy a new CV joint and replace it and keep your original axle.
I was suspicious of that as well so when I was moving things around I was sure to look at the outer part of the CV to be sure it wasn't moving. It appears to be locked in place.

Anyhow, slop in the inner CV could very definitely be the cause of a drive train vibration that is worse under load and the coincidence of 3x wheel rotation is amazingly strong.
Agreed. I tested again using the other app you recommended and it showed no spikes above the 49 hertz I was getting from the first vibration app. So that's definitely the vibration associated. I'm pretty sure this is it, that's why ordered a replacement axle. Should be here next week, so, weather permitting, I'll get the axle replaced weekend after next.

Suddenly my car is just shaking like crazy feels like all four wheels are off balance like a full pound.

Maybe it’s weather related.





Yeah I guess I didn’t pack the snow in quite evenly enough.

That's something we never have to deal with here. 36 degrees and everyone is bundled up like eskimos. lol

It's a balmy 18° I can't use water to spray out the remaining snow and ice so I had a pretty jiggly ride home last night. I have a friend with a heated garage so I may be making a visit there

Do you have a heat gun?

Yep but would only work if removing the wheels to get inside. I also have map gas torch which outputs 20-30x the heat but it's at a job site an hour away so maybe I will jiggle my way there tomorrow and fix with the torch. I knocked out most of the snow/ice half way home from Chicago last night since I had a max speed of 50 before making that pit stop.

I've had the snow in wheel shake many times over the years but usually the temp is close enough to freezing I just spray off with a pressure washer.

Not the greatest idea at 7° F even 18° it is today.

Glad I don't have to deal with those kind of temps.

How about a self-serve carwash with a spray wand?
