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

[Baloo]

I worked at a Chevrolet Dealer for 22 years. Aftermarket suspension lifts and lowering do in fact cause things to fail prematurely. Talk to an engineer if you don't understand this, but it's probably more like you don't want to understand this and just put the blame on Ford.

Yes they do, but explain why stock suspension CV axels are failing.

Use tremors on the std ecoboost

about $ 405
The boots and grease suck on all of them.
Hybrid needs an equivalent to tremors .
Comparison of tremors to hybrid proken pass side i have too.

Nice socks............

In reviewing this thread, the nay-sayers sound a lot like the same folks that chimed in on the new Bronco threads about failing 2.7L engines back in 2021. All the same crap while others just wanted to put some documentation together / have shared experiences on what was happening with zero out of Ford. They ended up roughing out the engine date of manufacturer range that were suspect.

Guess what came out last week...RECALL for 2.7L engines for roughly the range the forum figured out on their own.

On topic, good luck folks and keep documenting your occurrences so that maybe it helps some others.

I'm going to guess it's a Vendor that maybe didn't follow Ford's specs exactly unless Ford's engineers just screwed the pooch. But I still would like to hear the percentage of totally stock Mavericks VS modified Mavericks that have failed.

Just trying to figure out your original comment saying it is modified when stock has had issues too.

What are the part numbers of the tremor axles left and right? I wanna get a set to have on standby.

My original comments are valid. Modifying suspensions does have an adverse effect on the operation and reliability of drivetrain and suspension components. My original comment was over a week ago however, and I didn't realize at that time that there were totally stock Mavericks having this failure.

So, licensed upfitters have issues?

Maybe the reason I haven't had any issues is because the lift I chose was from a Ford Upfitter. You know one who's engineers work with Ford engineers to design products for future and current vehicles? Like Rousch, Shelby RTR and others.

Yep. Factory lifted specialized vehicles have been engineered and are nothing like aftermarket lifts. Lots of parts are spec'd and different on factory lifts to ensure proper geometry that ensures reliable operation.

Droves of Shelbies, Rousch and RTR vehicles have issues.

Not talking the stealerships that pit on Rough County and other lifts and then sale the vehicles at outrageous markups.

I can go into a Ford Dealership and order a Rousch, Shelby or RTR vehicle. I do believe thei4 engineers work hand in hand with the vehicle design engineers. Case in point Rousch helped design the 2005 Mustang, how do I know, because I drove a 2003 bodied Mustang in 2004 that other than the body was a 2005 Mustang up and down the Woodward Dream Cruise. Rousch was testing stuff for Ford which didn't want the 2005 Mustang seen on the streets.

Ford upfitters work extremely close with Ford. Bronco Raptor RTR helped design.

Look back a few posts in this thread i posted my reciept with part numbers , about $405 for both .

Just for documentation, my truck started to shudder, and vibrate just as described in this thread a week ago. Took into local Ford dealer where I purchased it 2 years ago and they replaced the left front axle under warranty. 21k miles. I was able to suggest to the service writer what I thought it was based on the great input on this forum so they didn't have to look to hard to find the problem as described.

The more data, the better the analysis. I say collect as much as possible. People with NO lift or lowering are sometimes having problems. Seems like this is possibly a weak link in our mavericks. Although, the internet does tend to amplify bad news over good news.

I'm at 3200 miles, so I don't think I'm a good candidate for issues - yet. I won't be lifting or lowering mine. Might take a stab at those 235 tires a couple of years down the road, same size as the tremor, but that won't change the suspension geometry.

I have a 1" level on mine, so we'll see what happens. When they do go out, if nothing aftermarket has came along, I'll go with the Tremor axles.
I'm like others in thinking there is a basic issue here from the start. A 1" lift changes the angle of the axles by maybe 3-4 degrees, nothing that should cause them to wear out in 15k miles. And all the stuff about using "approved" parts to lift them, a lift is a lift, no matter how you go about it. You raise the transmission above the hubs that amount, the axle angles are the same, puck, spring, or magical magnetic elevation, the change is the same.
But, compared to some of the other manufacturer's issues, the axle thing we have is a minor irritation..

People selling products have no ties to FORD's warranty. Including Shelby and RTR. They are private companies. If a dealer choses to back their products that's on them. Even still, FORD can deny the warranty for the modifications done, even after the dealership says otherwise. Would they? Likely not.

And pucks are pucks. There is nothing good about them for suspension. The end. There is ZERO difference between and RTR puck and a RC puck. Materials used, maybe, but the angles and changes made are the same.

Some of ya'll confuse these products as being reliable by who they are made and it's got nothing to do with the side effects of lifting a vehicle. Ask yourself why every manufacturer that uses a "lifted" version of their suspensions, ie. Tremors, TRD, Raptor etc etc why they don't use pucks. Ever. And why that stock lift is so minimal compared to the normal versions of said vehicle, if anything at all.

Yes, stock setups are failing. That's great info. The bad info is when people come in blaming FORD for their modifications done. Most reports of stock failure are on FWD Hybrids. The next one? You guessed it, modified suspension across the board.

If we want FORD to address it, they need to see it's 100% on them. Not 50/50.
