I have a 90 F150xlt 4x4 5.0 when I step on the brakes it pulls to the left. I have to countersteer to the right to go straight. Now when driving it will pull to the left also and once again I have to turn the wheel to the right to go straight. I have had the alignment checked, turned out good, changed both front brake calipers, both front brake lines, pads are good and so is tire pressures. The left front brake caliper was producing a lot of heat and also the way it was pulling made think it was the problem. Well the new caliper solved the heat problem but not the pulling to the left. I am out of ideas of what it could be causing this unless some how brake bias has changed. This seemed to happen after a tire rotation, backs to front and fronts to back. I kinda doubt this is the problem though. Now I am tempted to put the lefts on the right and the rights on the left but I doubt that would do any good. I am just out of ideas of what is causing the pulling problem.

 

I think it could either be your radius arm bushings or your ball joints. I had that problem, then I had only my left side ball joints replaced and a radius arm bushing fixed, it fixed it but now it pulls to the other side all the time. I'm sure when I replace the others and get an alignment it will be fine.

So yeah you could have a shop or yourself look at the ball joints and bushings and see if they show too much wear.

 

All of those was good. I had a shop check out my steering components when I had my alignment check. *PUZZLED*

 

Wierd... they'll usually go for ball joints even if they're good (it's a big repair bill for a relatively easy job).

My truck does this to a minimal extent, but not all the time. I've checked all of the same things you have... Hopefully someone can figure this one out because I'd like some ideas too!

 

I know it's pretty much bs! If I rented the tools how hard would they be to install yourself?

I swear the part is only about 15-30 dollars and I had to pay about $500 to have only one side done.

 

The only odd tools you need are a pickle fork and a ball joint press. your local parts store might even loan them to you.

Aside from that, and the cost of the ball joints, it's a nice Saturday afternoon job. Kinda depends on how things go, but maybe 4-6 hours to do both sides?

 

Mine pulls all the time. I have good stopping power. I drove the truck a little hard last night to see if driving it and putting heat into the brakes would solve anything but that didnt work either. All I know is that my brakes are cooler now with those new calipers on.

 

How about the wheel bearings, did you inspect them too?

You said it's a 4x4, is one of your hubs stuck locked in? It could be broken internally and be locked even if in the unlock position.
