Put your axle nut back on with about one nut thread still showing, Put an air rated impact socket on the nut. Spray the pline section with WD40 or Liquid Wrench and start hitting the axle towards the engine with a good sized sledge. The sicket will keep you from damaging the axle and the nut will keep you from damaging the threads if done right. DO NOT APPLY HEAT. This will warp the spline. If this doesn't work, call a wrecker and have it hauled to a shop where they have the big guns as the axle and hub may have to come off and be separated. I have had this happen. Please rate as helpful or fixya.TY

Okay, more than likely you are going to need to take the upper and lower arms in to have the old joints pressed out and then pressed in. If you can buy the replacement joints and take them in, you will save a WHOLE lot of cash. You could also do this yourself if you have a hydraulic press or, if you can swing by an auto parts store that rents out tools......it looks like a modified c clamp.

hit the steering knuckle where the ball joint shaft goes through it while u have the wedge/pickle fork inserted, u do this on the round side of the knuckle, this is what is called a "Morse Taper" hitting it distorts the hole a little and that lets the joint pop free. You need at least a 5 pound ball pen for this to work..

there's no torque setting that you go by because there aftermarket!
the factory ones are riveted in so you won't find it any where.
but when i do them and do them . witch is alot. i go by the feel of my air gun. if you are using just hand tools then i would use a 3/8 ratchet and tighten it as much as you can with that set-up , then get a 1/2 set-up and turn another 1/4 to 1/2 turn.
if you need a number for a torque spec then depending on the grade bolt that came with the replacement ball joint. a 10mm bolt thats a 8.8 grade will only do 33 ft. lbs. before it will strech and then break. so no more than that! 8.8 is the most common for automotive grade hardware...
good luck man

You will have to unbolt them. But Check them first. They are likely loose . Blazers are hard on lower ball-joints and it will be a good time to change them at the same time if they are bad.
