Yep....need accel data to process through our fft analyses. to analyse the datal
Im not sure the exact s
I'm not sure the exact speed but I would say it was definitely under 15 km/h which is about 9.3 mph. I'll be interested to hear if the larger shim gets rid of it.
This is the main reason I'm not taking mine in. My vibration has always been there, but not bad or annoying enough for me to subject myself to inept dealer service departments.
My honda was out of warranty. The dealership sold me new tires and then said they did not support manufacturers warranty when I identified a problem. I went to the indy guy who provided a professional opinion and the honda dealership refunded my money on the tires once I got replacements and gave they back the dunlops they sold me. This was a somewhat long and messy process.
How do you know the 2020 Lariat don't have this problem? I have to wait 3-5 days for the dealership to get the part. Ultimately if they can't fix the shudder than I'm going to ask for my money back and tell them to call me when the 2021s come in.
I test drove a 2020 Lariat that did not have the issue. Only one I test drove before I drove this one. On the test drive, I immediately noticed the vibration/shudder/bucking/insert your own description and remarked on it to the salesman, who was in the back seat. He gave me a lame ass excuse that it was because it had been sitting out in the sun. I should have known better, but I had done no research on the vehicle. Had I known of the issue, I would have left it there. But nooooooo. It was certified pre owned with 12K miles, and a long warranty. My bad. Where I was really pissed off was when the dealer service department (at this and another dealer) did their dead level best to convince me the vehicle was operating as designed. I know, because they both produced another Ranger with the same characteristics, that Ford put them up to it, to make us think it was normal and go away. As someone else on this forum noted, "The fact that there are more than one vehicle with this issue neither makes me feel better nor fixes the truck." The service people at the dealership had know idea that the TSB had been issued, and I printed a copy with the instructions for them to perform the work. They refused to order the shim kit until they had examined the vehicle. They were totally focused on the 10 speed transmission being the problem and were surprised that the focus had shifted to the rear axle. They refused to do the TSB work, telling me the rear axle pinion angle was within specs of 5 to 6 degrees. From the information I had obtained here (Thanks, Phil Shilke) I already knew it was an issue with the driveshaft/center carrier. I am not optimistic it will be fixed, but with luck, I will get some relief.
Round 2.......
I was researching yesterday and called a place that does 4wd builds and the first thing I was asked was whether Ford was shimming the center bearing.
I got a similar response from a friend just after I got my truck. The only problem is his shop is five hours away and I don't want to mess with my warranty.
Since very few vehicles have this problem and it’s not a safety issue - not likely at all.
