I have a vibration in the front left side when I get at 35mph. Stops before you get to 35mph and after ward.
Best 4x4 I know of, I mean you have to drive it to believe me.
The truck has so much torque that I had to chain the motor to the frame, plus I had to change the drive shaft out for a much stronger one because I thought that the thing was gonna break from the horse power.
I disagree I own a 1989 F-150 XLT 5 LITER. I do not find it to be that powerful even with my uprated camshaft and ignition. As for chaining the motor to the frame, you should have just replaced your bottom motor mounts.
I have owned Ford trucks for years, and I have never found a 5.0 that knocked my socks off. Don't get me wrong it's a good motor just not loaded with power, and gas mileage was bad for no more power that it had. If you want power from a factory Ford gas motor buy the V10. This motor performs like a champ, plenty pulling power and speed, the best of both worlds and still will get around 14 mpg, at least mine dose. It pulls a 40 foot camper with ease and, when empty will accelerate as good as todays police cars. I know this for a fact I drive a police car daily. Even with all that I still do not need to chain the motor down.
I have to say I've never had a 5.0 litter motor in my truck did not need it my 4.9 six does the trick it will go anywhere you need to go and will haul anything you need also I have had to change my motor mounts many times.
