2000 Chevy S10: passenger side as I..tire..wheel bearing..steering

Resolved Question:

I have a 2000 Chevy S10 ZR2 Pkp. I need to replace the half axle shaft on the passenger side as I recently punched a small hole in the tire side boot while drilling out the rivets on the lower ball joint. How the heck do I seperate the wheel bearing from the steering knuckle and the spline? I tried hitting it with a BFH but no good. Is there a special puller? Anyway what is the proper method for replacing this piece? Do I need to disconnect the tie rod from the knuckle?

   I'm trying to picture the job you are doing; have you somehow managed to remove the lower ball joint without removing the knuckle or axle first? Is the lower ball joint still tightly installed?

Ok here is what I have done. I removed and replaced both the upper and lower ball joints on the driver and passenger side as well as the idler arm, all of which were shot. The upper bj on the passenger side was easy enough with a drill, hammer and a pickle fork. At that point I had removed the Brake caliper, rotor, and axle nut. I tried romoving the wheel bearing with a hammer like all the posts said to do but after hitting it on the back side a number of times it wouldnt break loose. However, the knuckle at that point had just enough articulation to remove and replace the lower ball joint with the axle shaft still there; very tight squeeze as the CV boot butted up against the lower control arm. At this point both bj's are installed and torqued to speck. My question is, what parts do I need to remove i.e. outer tie rod, wheel bearing and, etc. to replace the half CV drive axle on the passenger side and how do I remove them i.e. two jaw puller?

Here are the steps for removing the axle from the service information for your truck; this is all after the brake caliper and rotor are removed:


   Remove the axle nut and washer
   Remove the brackets from the upper control arm holding both the ABS wire and the brake hose
   Remove the ABS bracket located on the top of the upper control arm ball joint.
   Position a safety stand under the lower control arm
   Disengage the wheel drive shaft from the hub by placing a brass drift against the outer end of the drive axle in order to protect the threads. Sharply strike the brass drift with a hammer. Do not attempt to remove the axle at this time
   Support the steering knuckle and assembly with a piece of wire in order to prevent damage to the outer tie rod and ABS wire.
   Remove the upper ball joint nut and separate the upper ball joint from the steering knuckle
   Remove the lower shock absorber bolt
   Remove the lower ball joint nut and separate the lower ball joint from the knuckle.
   Remove the axle from the steering knuckle assembly. Important: you may need to lower the safety stand from the lower control arm in order to relieve the pressure of the torsion bar and in order to allow for clearance.

   There really is no secret or special tool needed to separate the axle from the wheel bearing other than a large hammer and a punch (so as to not damage the threads on the axle by hitting it directly).    These can become frozen over the years; sometimes a liberal amount of penetrating oil and a LOT of force may be required to drive the axle loose from the wheel bearing.
    If the punch does not work, I sometimes use a block of hard wood positioned over the end of the axle instead of the punch; this allows a harder swing of the hammer.    I usually use a 3 lb sledge hammer for this job.

So a block of wood butted up against the end of the axle shaft where it has that dimple? Once I seperate it from the bearing, how do I pull it from the diff? Can I pry it with a slotted screwdriver or does it require snap ring pliers? Thanks for the help.

It will just pull straight out of the differential (unless yours is one of the type with 6 bolts holding it to a stub axle at that end; I don't recall which type you have on that year.(. If you dont see any bolts around teh inner CV joint, it just pulls out.   using a pry bar to help may be necessary.
   Yes, just drive the axle inwards to free it from the wheel bearing.

   If the hole in the boot is very tiny, sometimes a small dot of RTV silicone gasket maker will seal it...
