Body mounts

[RRlocoENGR]

I have a 1999.5 F350 and love my truck...life is good! I have a Predator tuner, 4 inch exhaust and Air Raid intake. I tow a 40 ft. toyhauler weighing in at 15,500 and it does well.

I have noticed a bump or thump under the truck and thought it was the front end loose or a worn out part in the front end. Today I had the truck aligned and the mechanic told me all was well with the front end parts.

I put new Bilstein shocks on all corners which smoothed the ride tremendously, but I still have a thump or bump under the truck when I hit bumps.

I am guessing it could be a body mount bushing since I have found one that seems loose or worn. Does this seem like a possible source of such a noise or feel in the body or chassis?

Thanks...is this normal repairs needed to the F350 to keep the ride smooth?

Check your sway bar end links to see if they are tight. I had the same thing happen to me so I took them all apart, soaked them in red loctite, and cranked them on. Havn't had any noises since.

Yup, sway bar endlinks....Try removing your sway bar and hitting some bumps with it off....If it doesnt thump anymore, its your endlinks...Do you feel the bumping under your left foot when driving? If so its very likely this is your problem.

You know exactly what I am talking about! You feel it under your left foot on the driver's floorboard.

Jack the front of the truck up one side at a time , tires off the ground about 2 inches. Slide a long bar under the tire and lift up and down, this works well eith two people, look at the ball joints while doing it. Then do the other side as well. I bet your front end man missed this small thing as been through it 2 times until I did it and found out that the right side was the worse worn side then the left but the sound and feel of the thump travels all over the truck. I even did the sway bar 1/2 inch bolt mod to at the same time. The right side ball joint was so bad it rattled in your hands when you shake it. Good luck and let us know what you find.

Thanks for the info on the ball joints, I was seriously thinking about going back to my front end shop and get them to check it all out again. I am like you, believe it could be ball joints or sway bars that he missed.

It really is nothing major, but when you know your truck, you know something doesn't feel right!

Still have not found the elusive culprit, but gonna change the stabilizer links since the bushings look worn. Hopefully that will end the noise I have heard since I got the truck!
