Hello. I am going to have to replace my ball joints soon, and have a couple question. The thing I am worried about the most is the pinch bolts. I live in Michigan where in winter they salt the roads, and corrosion is worse. My truck is a 93 Ranger rwd, with the twin i-beam suspension. I am afraid to put too much force on the pinch bolts and snap them.

What are some good tips for getting these loose without them snapping? I already sprayed some PB blaster on them and am going to let that sit on there for a couple days. Would a propane torch be good (or do I have to use mapp gas)? Should I try to get heat on the bolt itself? I've never done ball joints on this truck before, so any extra tips would be greatly appreciated.

BTW, the truck has 98k and it doesn't look as though the ball joints have been replaced ever (they are the sealed ones). Thank you.
 
I ended up having to drill mine out and re-tap the hole it was a serious PITA, there is a risk with heating I-beams that when they cool become brittle and can crack. I have seen people drill out the threads and use a nut and bolt through the beam, where I live uses alot of salt in the winter as well plus its coastal here and we get alot of salt in the air from the ocean so I know your pain
 
Do you think that I could heat the bolt itself, and perhaps loosen up the rust? Sounds like a pain... lol It seems like it would've been better to just have a nut and bolt instead anyway...
 
Heat the pinch area, not the bolt.
 
I didn't have much of a problem undoing mine. I live in north central Indiana (~10-15 minutes from the Michigan line). IIRC, when mine would start getting tight while removing it, I would change directions and run it back in, then back out and repeat going a little farther every time to work it out. I was even able to reuse them after cleaning them up after that.
 
I pulled the one in my truck for the first time ever a few months back... it's a lil newer (96)

I just heated the pinch area with mapp gas for a minute or two after having PB sit there for a week... Came out like butter...
 
Ah thanks for the tips, I feel more confident about getting this done without issue now. :D
 
One more quick question. Does anyone know if the Spicer professional grade, or TRW ball joints are made in the USA? I bought some Mevotech joints at about a mid-range price, and they were made in India/Taiwan... I thought they would've been made in Canada (since the company is based there). Stay away from these ones. They were missing grease fittings, and their seals were messed up.
 
Not to be annoying or anything, I just wanted to mention that the Spicer Professional grade ball joints are made in the USA (in case anyone else wants this info). They look to be high in quality. I got all 4 from RockAuto for a song.
 
Hey bd,

How did the ball joint job go? I have the same generation truck w/twin i-beams and I'm looking to do the same as you, so any help or tips are greatly apprectiated.
 
It went great. Just be sure to apply pb blaster on all nuts (tie-rod, lower ball joints) and pinch bolts, and let it sit for several days (apply it a couple times or more... the more the better, and the longer it sits on there the better). Have a pipe to put over your ratchet to break the nuts loose. Loosen the tie-rod end nut first (after you remove cotter pin). Pinch bolt next. The last nut you loosen is the lower ball joint (after you remove the cotter pin). Don't use a pickle fork to break the ball joints or tie-rods loose. All you have to do is loosen the nuts, flip them around (so the castlelated part is facing down), make it flush with the tip, and hit it with a dead blow hammer. They will come loose after a few wacks, and you won't damage the dust boots. You'll want to string the tie-rods up, out of the way while you work. Be careful with the pinch bolts on the upper ball joint though. Put a little bit of heat on the pinch area, and they should come loose no problem. Remove the pinch bolt. When the pinch bots are out, pop the alignment bushing out of the upper ball joint with a screw driver (mark it first if you have an aftermarket bushing, so you know how it goes in. My stock bushing only went in one way). Turn the spindle to get to the lower ball joint, loosen the nut, flip the nut, whack it many times on the top, and the ball joint will come lose. Now you have the spindle loose (ball joints are in the the assembly with the spindle). You're going to need a ball joint C tool (kinda looks like a c-clamp), which you can buy for about 35-40 bucks at harbor freight (or borrow at an auto parts store). I popped the old ball joints out using this tool on the floor. You will need the pipe and the ratchet. I prefer this over a breaker bar. The ball joint will literally pop when it is loose (takes a little grunt). Then it will smoothly come out. If you buy the harbor freight ball joint tool, you have to remove the lower ball joint first, then the upper one (the upper one has a snap ring on it btw, remove it with a screw driver and pliers). When you install them, you install the upper first, then the lower. The lower one just gets pressed in, there is no snap ring that goes on it. When you put the upper one in, be sure to put the snap ring on it. Be sure you know when the ball joint is in all the way, check several times, because you will damage it if you keep tightening. When you put the spindle back on the truck (make sure dust boots are on the ball joints), finger tighten the lower ball joint nut. Then put in the alignment bushing on the upper ball joint and put the pinch bolt in, loosely tighten it (like finger tight, just make sure it's started into the threads). Then, put a bottle jack underneath the lower ball joint, and put some slight pressure on it (to keep it from moving while you tighten the nut. Then, using a ratcheting torque wrench, tighten the lower ball joint to 35 ft lbs. Then, tighten the upper pinch bolt (on the upper ball joint) to 85-100ft lbs. Go back to the lower ball joint, tighten the nut to 104 ft lbs. Tighten it a little more if you have to, to make the nut line up with the cotter pin hole. Tap the cotter pin in and bend the ends of it. Put the tie-rod back on, torque it 51ft lbs, a little tighter if needed to line up the cotter pin hole. Tap cotter pin in and bend the ends of it. Put your grease fittings on, grease them... Enjoy your new ball joints.
