Sway Bars

Does anyone happen to know the size of the large nut that holds the coil spring onto the i-beam? I'm going to the junk yard in the near future to get the front and rear sway bars for my 85 F-150 and the yard I'm going to I have to bring my own tools and I have to buy a socket to get that nut off the donor and my truck to remove/install it on the front.
Thanks in advance, Mike

I don't know. Can you get in there with a measuring tape?

Arn't they all the same size? Sway bar and not? If so just measure yours.

I'd measure mine, but it's packed with ice at the moment...

i have an 82 250 with king pins so it might be a different size than what you have but mine was 1 1/8". get a lot of spray-lube and a big breaker bar.

With my past adventures to the junk yard no sizes ever match up, but worth a shot. This project will have to wait until next week because I'm going TDY for the week. Thanks for the thoughts and I'll check back in and let ya'll know how it goes when I get back. On a side note, does installing the front bar make that much of an improvement for the work involved or will just the rear be enough?

Mike

As a general rule, if you are going to run one bar, always make it the front. And the front bar is always larger than the rear.

The factory always designs a car to "push" as Nascar calls it, in a turn. They say if you go into a turn too fast, and the frontend keeps going straight, the natural tendency of most drivers is to hit the brakes, which with a vehicle pushing in the turn, will correct it quickly. A sway bar up front, will always keep the designed push in the vehicle.

With a sway bar in the rear, it will make the car more "loose" in the turn, or on other words, coming into a turn too fast, the rearend will have a tendency to slide around on you. So if they have a rear sway bar, they always have a larger one in front to keep the balance front to rear so the car will push in the front.

okay, i'm still planning on putting sway bars on my truck, but that is by far, without question, one of the best definitions and explanations of why sway bars work. i'll give you a nice high rating, cause that was worth it... thanks
