PXII Vibrations/Shaking

[DavidH]

Hi Guys
I have been reading through a lot of these post hoping to find a solution to my excessive Vibration issues which is noticeable at 60+kmph and get worse the faster I go.

My 2018 PXII ranger GLX has a wild vibration which gets more and more pronounced the faster I drive it, you start to feel it at 60kmph and as you increase your speed to 100km+ you feel it shake, the interior shakes, you see your phone shaking on the passenger seat and it feels unsafe at speeds over 100km.
My Ranger has done 80,00km and the vibration kicked in after I had the 45k service completed by the local Ford dealer.
I have been trying for the last 18 months to find a solution to the vibration issue, all at my costs. I have had the dealers look at it, no luck there, standard speech from them, tires need balancing, didn’t notice any vibration, tires have a 10g bubble or the best is, it is consistent with the make and model – new rear springs and tires will fix it but not covered under warranty.
2 independent workshops both committed to finding problem without any luck, but both drove the car and identified the vibration as a issue but unable to resolve or pin point the cause.
I waiting to have another discussion with Ford Australia regarding the issue and would welcome any solutions feedback to this problem if anyone else has experienced or is experiencing the same issues with their Ranger.

Thanks

Have you tried swapping the wheels/tyres with another Ranger?
Does the vibration feel like it comes through the steering wheel (front end issue) or through the seat (rear end issue)?

Tail shaft harmonic balancer got dirt in it? cheers, Butch.

I imaging the wheels and tyres have been balanced as one maybe out of round ur have a lump on one of the tyres. You won't see chid looking at them.

One of the three tai shaft uni's could be stuffed and as butch said check the inside of the tail shaft balancer for mud..

I have replaced the all 4 tires a month ago based on the advice from the local Ford dealer and it has made no difference to the vibration,

The vibration feels like its under the center of the car and shakes the whole cab but no vibration felt through the transmission selector, I don't have a tail shaft harmonic balancer, I have checked and cleaned around the centre tail shaft bearing which appears to be in good condition.

Myself I would have the tail shaft pulled by someone like Hardy Spicer and have it checked and balanced.
I have had unis feel ok, but when pulled apart they are well on the way out.

I have spoken with Ford Today and they are going to talk to their technicians regarding the Vibrations and will let me know what they come up with then refer me back to the dealer for more checks, I did Mention that the tail shaft might be out of balance so I'll wait and see

I don't know if this is related but this is what I have experienced in my PX1

- vibrations experienced at high speeds = wheel balancing and alignment (this solved issue for me)
- vibrations experienced at slow speeds = check driveshaft balancing/rear axle/transfer case (I had the rear axle collar/balancer changed just yesterday and vibrations disappeared. According to my dealer, this was normal wear after 140K km

Hopefully, you're able to sort it out.

Another thing to check, when the tailshaft was removed to take out the balancer, maybe it wasn't re-installed straight? There is a lot of adjustment in the 2 centre bearing mounting bolts, care needs to be taken to get it right.
Also check if the tailshafts are at the same angle. Using a level app on your phone is an easy way to do it. If there are any discrepancies you can add washers to the centre bearing mount to adjust it.
Just a couple things that can be easily ruled out.
