The dealership I bought it from is out a month from now too, guess that's the norm these days. We'll see what happens in September if it don't self destruct by then...
It stemmed from a 2019 rcsb purchase because they were the only dealership in the area with the reg cabs. I'm kicking myself for not ordering this one locally.
I hear the 10r80 whine too but there is also a whine coming from the rear too. The rumble strip feeling is definitely not the lane change feature unless they installed it in the seat and gas pedal as well.
2021 F-150 xl 5.0 bought new from an out of town dealership, I'm experiencing whining pretty much at all speeds but loudest at 68-70mph when trying to keep steady speed. The whine does disappear when I took my foot off the throttle which would indicate a pinion bearing on its way out. I'm also...
I was given a rental no questions asked when I had service done at the dealership I bought it from, unfortunately that dealer is a 2hr drive. My local dealerships are a hit and miss.
The Corsa side exit is loud but only when your foot is down, idle is pretty quiet except for cold-starts. I would imagine the single rear exit would be even less noisy.
I used Oz for my procharged 13', and the 19' when they were using the Ngauge. I still have the damn thing and I don't remember if I unlocked it before selling the truck.
I have 3 different sets of wheels for this truck and they all have the vibration, and guess what...The dealership blamed it on the 20in low pro tire and my truck being a RCSB that was never optioned with 20's.
Well, I don't have a front diff. but I always had a feeling the culprit was in the rear diff. I have another appointment next week so fingers crossed...
I'll probably just live with it until I can find a Bronco to trade on, I don't have time nor do I have the patience to go back and forth with these dealers and be without a vehicle.
I don't have 4wd so it can't be the IWE's and the driveshaft was replaced, so I can eliminate those as the issue. I also have 3 different size wheel and tire combo's that all produce the same vibration results. I have a feeling the issue is in the rear end or transmission. I guess I'll just keep...
I'm in the exact same situation, I can't seem to get anywhere with the local dealerships either. I'm thinking the only way out of this is contacting a lemon law attorney.
My truck has the same exact issues with the AC blowing hot air but of course I was never able to duplicate it for the dealership. The rear end shimmy that has been looked at twice by different shops and they keep giving me the same BS conclusion that it's normal.
I've taken it to 2 local dealerships that have got me nowhere, first one changed the driveshaft and then told me it was just a characteristic of the RCSB's. Second dealership said the tires were out of balance but then when the problem still existed, they too went with it being a characteristic...
