My thoughts on CV axles - possible design flaw? (self replacement, tear down, tips on DIY-ing)

[akarol]

I drive a 2022 hybrid and I am needing to replace my axles a 2nd time due to vibration while accelerating. I do put a lot of miles on it as I am almost at 120,000. However, this is obviously a design issue and something that Ford should address.

I am thinking of requesting the Tremor ones (PZ6Z-3B436-A & PZ6Z-3B437-A) as I see that they are beefier? Does this make sense or is there a superior aftermarket one that I should consider instead.

Thank you in advance!

Tremor's CV don't fit hybrid from what I've read.

Tremor ones will not fit, shaft lengths are different.

Ford designed new one for the Hybrid that came out in the fall of 2024, we haven't heard any complaints about the redesigned ones yet. You cannot even get the ones that shipped with your truck from the factory anymore.

Well, I just got my car back. Replaced both of my axles with the latest (3rd gen) versions after having it already replaced with the same original version back in 02/24. Whopping $1,334 after significant discounts by the dealership. They had it at the shop for over a week trying to get this replaced for free due to it having been replaced already. Ford will only cover warranty parts for 1 year, which I surpassed.

I am extremely frustrated and will honestly never purchase a Ford vehicle again. I put a lot of miles in - 120,000 in 2.5 years - and got completely screwed because of it. The icing on the cake for me was the lack of accountability by Ford. I have called over a dozen times in the recent week to their Customer Support number and spoken with many reps who all tell me that there is nothing that they can do. No escalation, nothing. A dead end on something that is a safety concern and can eventually kill someone.

Ford doesn't care about their customers so I will stay away from them in the future. What a shame... I absolutely love this truck and had vowed to purchase the current one when I am ready. I guess I didn't mind the many recalls as they were all covered but am now concerned about what the future holds.

I thought they might fix them for free up to 150k (through the customer
satisfaction program). But why only the 22’s when 23 model year was also affected???

It could be expanded later to cover more production dates, pending failure data/parts inventory. I just turned 60K on my original axles, no issues so far.... (I'm in the covered production time, so I will wait as long as possible).
