My truck shakes at 90 MPH

Id say it's limited more so because of tires and driveshaft. I've been over 100 mph in my truck and the motor/trans isn't screaming at redline. Powertrain can handle it.
Driveshaft and tires On he other hand, won't hold up to sustained speeds like that. My old tires were rated for 112 mph so I decided to see if the truck could actually do that. And it did lol. Was sketchy, but it did it.

Mine has a shake around 68-70 now. I replaced the U-joints and that got rid of the 60 mph shaking, but the tires have a slight cupping and have been rotated. After the rotation, that's when it started, so I've been playing with the air pressure to help wear in the tread. So far it's worked fairly well.

Have you ever had yours removed?
#9
Yep. I had mine removed. I have it back on now though since my new tires are only rated to I think 99. So I don't wanna be tempted to go over 100 again lol.

A number of years ago, Ford had to issue a recall on the AWD Aerostar vans because of driveshaft, u-joint and transfer case failures caused by driveshaft whip at high vehicle speeds. They seem to have learned their lesson.

The powertrain should include torque converter or clutch, transmission, transfer case, driveshafts, differentials and drive axles. Many, including Ford, define the engine as part of the powertrain as well.
The term drivetrain is often used interchangeably with powertrain. It probably should not include the engine though.
There can be some variability in these terms, especially when it comes to things like a new car "Powertrain Warranty". Best to read the fine print carefully.

Vehicle shake...
Jesus Christ, Gentlemen...I went out of town for Thanksgiving. Some of the Interstate and most ALL of the major Texas highways are limited at 75. I have larger tires and am just too frickin' lazy to figure it out mathematically. Quick calculations...with 31" tires, which are about three inches taller than stock...figures, roughly an 8-10% speedometer error. I judge my speed by way of my GPS. When the GPS reads 80...I set the cruise control. GPS don't lie. if it says you're going 80...you're going 80 no matter the speedometer reading. I can only remember one time I ever took my truck over about 85. But i gotta hand it to those of you that flirt with 100 mile speeds...my ***** just ain't that big, I guess.

wait.. first.. your yelling us that your factory tires were 28 inches tall? its an edge right? that doesnt seem possible.. my factory tires on my sport wer like 30-31... also.. why were you going 90 in a ranger. they suck at 75.. also search before posting a question thats been aske 90000 times

Before we even leave the blocks let's get on the same page, Partner...I never asked any question nor did I ever claim to have pushed my truck over 85...and that was with stock tires.
First off, I was NOT yelling at anyone. Nor did I use any words that could possibly be construed as being derogatory. My exclamation was a reaction to the idea that anyone would push a Ranger to the limits claimed. And my words were something to the effect I had pushed my truck to 85 only a time or two..
Second, the stock tires (as per the sticker on the door jamb) were 235/75/15's. By my calculations those numbers work out to describe a tire that is nine and one quarter inches wide and just a hair over twenty eight inches tall. Now those are Ford specifications for my truck, a 2002 Ranger with the Edge package.
I replaced my stock tires with 31X10.50X15's. That makes the tires I have now three inches taller than stock. Now, according to my mathematical calculations (and I freely admit I'm no Rhodes Scholar) the stock tires being 90% of the height of the tires I have now gives a speedometer error of 10% (i.e., my speedometer is indicating only 90% of my actual speed). Therefore, in a perfect world, when my speedometer reads 70 MPH, my actual speed is 77 MPH. When GPS tells me I am running 80 my speedometer reads just under 72 MPH. I suspect the fact that my speedometer reads just a little over the 10% figure I eluded to earlier is due to the tires growing a fraction of an inch due to centrifugal force acting on my tires at highway speeds.
I apologize if my post was mis-construed...I assure you that was not my intention to seem like I was making remarks that chastised anyone...ANYONE.
So perhaps it might be you that is misreading the posts in this forum.
Hope you had a nice Thanksgiving and I hope you have a nice day.
