Is Your F-350's Engine Mount Failing?
The engine mounts on your 1973-1983 F-350 are simple, but they take a lot of abuse. The combination of a heavy engine, high torque, and age can cause the rubber to crack, separate, or become saturated with oil and fail. When this happens, you'll notice some distinct symptoms.
Common Signs of a Bad Engine Mount
- Excessive Vibration: You'll feel a new or stronger vibration in the cab, floor, or steering wheel, especially when the truck is idling or accelerating. Good mounts absorb these vibrations; bad ones don't.
- Clunking or Thudding Noises: Loud clunks or bangs when you accelerate, brake, or put the truck into gear are a classic sign. This is the sound of the engine shifting and hitting other parts because the mount is no longer holding it securely.
- Visible Engine Movement: Have a friend watch the engine while you have your foot on the brake and shift from Park to Drive or Reverse. If the engine jumps or lurches more than an inch or two, the mounts are likely shot. You might also see the engine sagging or sitting crooked in the engine bay. 🎬 Watch: How to diagnose bad motor mounts in your vehicle
Choosing the Right Aftermarket Engine Mount
For a classic truck like the 1973-1983 F-350, original Ford (OEM) mounts are likely discontinued or very hard to find. The aftermarket is your main source for new parts. The most common brands you'll find are Anchor, DEA, Westar, and Pioneer. Forum discussions among truck owners suggest that these are generally considered standard, value-oriented replacement parts. While they will get the job done, some users report that their quality can be inconsistent. For a heavy-duty F-350, it's wise to inspect the parts before installation for any defects in the rubber or welds.
Pro Tip: When replacing engine mounts, it's highly recommended to replace them in pairs (both left and right). This ensures the engine is supported evenly and prevents the new mount from failing prematurely due to an old, worn mount on the other side.

Frequently Asked Questions
How many engine mounts does my 1973-1983 F-350 have?
Your F-350 typically has two main engine mounts, one on the driver's side and one on the passenger's side. It also has a transmission mount at the rear of the transmission, which should also be inspected for wear when you are checking the engine mounts.

Yes, for someone with mechanical experience and the right tools, this is a very feasible DIY job. The process involves supporting the engine with a floor jack and a block of wood, unbolting the old mounts, lifting the engine slightly, and swapping in the new parts. 🎬 See this walkthrough for changing mounts on a classic Ford V8 It does not typically require removing the transmission.
