Hi guys,
I live in Italy, and i purchased a 2019 Ford f150 lariat. 4x4 2.7L from Germany.

I have attached a link to a video , ive taken which shows the rear left wheel wobbling, and also the rear caliper and brake rotor wobblying also.
My car makes a whining noise, which i first thought it was the axle shaft u joints, So ive ordered a new shaft and u joints, as i also have a small dent in the alluminium axle shaft. So it could be unbalanced. i do have vibration at speed higher than 50mph.
My rear wheel wobbles and makes a chirping noise , as shown in the video at all speeds. .

My question is do i need a whole entire rear axle?
Can i rebuild the axle with a rebuild kit?
Can i buy 2 axle shaft flanges and replace them , both left and right..?

Does anybody know how i find the correct axle for my vehicle, and how to ship it to Italy.

thankyou for your help

if the videos dont work, just wait 20 min for youtube to upload them in 4k resolution..

thankyou again

Hard to really tell but it looks like just the axle shaft is bent at the hub. You should take the tire off and spin the hub by hand and see what it looks like to verify, might have to remove the caliper. You can enter your VIN on any Ford OEM parts site and it should tell you what part you need. Or, look up how to identify the 8.8" vs the 9.75". I do not know what trucks get what but they use both. C-clip axles are very easy to change out, probably lots of youtube videos showing how. I have done the same one twice on a Chevrolet before because the first one I got from a salvage yard looked like that. Might be good to do the bearing and seal as well but I got away without it.

Im seeing that brake caliper moving back and forth. Perhaps the brake rotor is not sitting flat on the axle, or the axle is bent.

SaltyBill

thats is correct i recently changed the rear rotors and pads, but i am 100% sure they where fit back on properly. All seated flat on each surface . It was wobblying before i changed both rotors and pads.
i think it the axle flanges that are bent or the axle shaft.

SaltyBill

I have ordered a new axle shaft . I hope that is it,
Could it also be the axle shafts that connect from the diffenetial to the wheel hub./ i can also order 2 new shafts for 200 usd each.

What part did your order? Looks like there's different parts for right or left, with or without e-locker, etc. The axle shaft should all be one piece like this:

SaltyBill

i have ordered the main shaft to the differential. from ebay . is this also called a axle shaft.. i get confused with the names..

im waiting for a reply for the exact measurments.
i would also like to order the two parts you have in your picture. what is the corrct name of each part?
I do have the E locker from factory.
where would the best place be to buy these too parts.

Don't load up the parts cannon until you have dug in to the hub. It sounds like a simple wheel bearing noise to me. But if it didn't happen before the brake job, suspect the brake job.

SaltyBill

It was there before the brake job. Its just now became louder and more noticeable. Ill have a look and remove the rotor ,caliper. I should eb able to see dmaaged bearing in the shaft?

If it is the outer bearing that is worn you should be able to wiggle it up and down (and get some movement). When you remove the tire do the same running test as the video and watch the face of the brake rotor. If axle is fine the rotor face should be stead/consistent with no wobble. From the video it looks like you have the 8.8 axle. There is usually a metal tag on one of the axle bolts that will identify the size, but looking at these two differential cover pictures I think you have the 8.8.


8.8


9.75




The items in the sketch above are called "axle shafts". The small pin like items will be the lug studs (6 per axle).






The driveshaft should not have a bend in the middle - that wobble in the middle you see in the video. That will 100% give you a vibration at speed. Usually with a vibration at speed I would suggest checking or replacing the U-joints, but in this case the driveshaft definitely will be contributing. If replacement is not an option, it would need to be rebalanced in its bent state.
