Left Front Axle seized

Changing out the wheel hubs - no problem.
Axle on the left front came out-should be no problem, put it back in.
Now, the left front tire will not spin-axle is seized.
Looks like I need to go into the front differential.

Will the axle shaft spin with the tire removed ?

Are the unit hubs and brake rotors mis-matched ?

You will need to measure both hubs and both rotors.

Won't spin with tire removed. Right side spins no problem.
Hubs are the same. Did a full brake job replacing the rotors while I was in there.

Did the unit bearing spin before you installed it? Have you removed the diff cover to check the spider gears?

Haven't remove the diff cover yet. Doing that either today/tonight or tomorrow.
Thinking something fell apart when I removed the drive axle, but nothing should have unless there was hidden damage from Oct.'19 accident.

Yeah unless something is broken, nothing should come apart when removing the axle shafts. I would suspect the unit bearing. Is it a new one?
Unless its the brakes, not having the right pads or rotor, maybe.

I don't see how it could be the brakes since it does not spin freely with just the hub assembles on and yet the right front having no problems / spins freely.
I'm getting antsy, as you suggested in the other thread, I'm going to take the diff cover off now, immediately.

New unit hubs should spin but may be very stiff to turn. The axle shaft and unit hub assembly should spin freely with or without the tires on. I would suspect grit or debris from the axle tube was pushed into the differential by the axle shaft when installed, or that there is spider gear damage.

it worked before you touched it? no noises, issues.

you say it was in a wreck? sounds like an issue... but are you saying that is why you replaced unit bearings? in most cases if it hit hard enough to take out a unit, the stub could be bent, so could the C or tube. wheel wound be bent as well.

no idea the miles here but if you had the axle/s out. the u joints might have been done. you have to be sure the tube is cleaned out as much as possible. you can make a rake that scrapes it out. putting back in i would grease the splines well. that helps to not cut the inner seal. or you will be doing that as well. depending on miles might be time to do it anyway.

I'll hopefully work on it later today, but the weather forecast is for rain.
