im not exactly following, are you saying the 3 link is better off tha n a 4 link setup? Im asking what the difference is between 3 link and 4 link. I know how it works, but which works better than the other, if at all.
Thanks :fordoval:
Not trying to start a battle here but here are my thoughts. Some don't agree but here you go.
1) The OEM steering is matched to a 3-link not a 4-link. If you put a 4-link on your truck you will probably get bump steer and you will feel it it in the steering wheel. It will also add additional stress on your steering box, drag link, and track rod as well as your ball joints. It does the same thing as changing a pitman arm and not changing the track rod bracket.
2) The rubber bushings in the axle are not designed to twist like the 4-link needs them to, so the bolts are going to work loose or it will tear up the bushings. Those big rubber bushings don't magically turn into uni-balls. They were not built to be used like that.
3) The 3-link is part of a sway bar system and putting a 4-link on a truck that came with a 3-link will require a bigger sway bar because there will be more body roll.
4) An item that may not be a large factor but still should be considered is at full suspension droop. The U-joint is at more of an angle on a 4-link and could bind up and cause a drive shaft or t-case failure.
