Today I installed the RH CV Axle. The only battle I had was extracting the axle - all YT videos show smacking the inner joint with a hammer - I even went to Lowes to get a heavier hammer, and that didn't work - see the section of all-thread and nut in the photos - I cut a length of all-thread to fit snugly between the inner joint and a bolt head on the PTU, then holding it with a pliers I backed the nut out and as it reached the end of its thread the axle was free to extract - way better than beating on it. The I noticed the friction material had come off the outboard brake pad - went to Autozone and got a set of new pads - found the same thing on the LH. The LH CV Axle cured the vibration but I could still just a little at exactly 60mph with acceleration - that is gone now. The inner joint on the RH axle had similar wear divots, just not as deep - the lubricant didn't run out like oil as was the case with the LH, but it looked an odd brown color.

Pity the oncoming drivers that will be blinded using LED's in the low beams.

Welcome. What you've written doesn't give us much to work with and suggest a fix and based on what you've written it doesn't look like you DIY. Any suggestions here we expect that you'll convey to what appears to be an inept "mechanic" which isn't ideal - it would be far better to seek the services of a local reputable real mechanic.

Wonder what's behind Ford switching from the 75-140 to 75-85 for the PTU ?

I've searched and contemplated switching but have stuck with the OEM trans fluid because of the mixed responses I found. This is what I was considering: Valvoline Multi-Vehicle (ATF) Full Synthetic Automatic Transmission Fluid

New CV Axle installed and a trip on the interstate confirms that was the issue all this time. Much easier job than the control arm replacement and with that said I might just go ahead and replace the right side. The old inner joint felt just a little rough and the reason can be seen in the photos - also the lube appeared to be gear oil, not a grease, or maybe it was grease when it started out.

@omar302 I haven't compared the in-out play between the driver's vs passenger side. The installed and the new driver's side does have some in-out play on the inboard joint which I accepted as normal. I'll be installing the new CV Axle this evening or tomorrow and will clean, examine and report on what I find with the inboard joint. Here's another report that makes me fairly confident that the CV Axle is my long ongoing issue. Car Vibration When Accelerating: Suspect Your CV Joint - HubPages .

No.

I don't think that the PTU can be ruled out - there's some influence on the CV Axle when turning the steering - it's going to take some exploration to clearly identify the noise source. I've got one of those "exploration" problems on my 2017 Sport - vibration when accelerating at speeds around 60mph - changed the control arm, that wasn't it - this weekend I'll be replacing the CV Axle.

This video is exactly what I'm encountering - CV axle should be delivered next week and I'll install it on the weekend.
