PB Blaster (actual name) is a rust penetrant/lubricant found at your local auto parts or Wal Mart that is known as a mechanics best friend at times due to its better than average penetrating properties. It cost a couple bucks more than other penetrants but its worth it due to time saved on those extra stubborn rusted bolts or that need to get lubricant into those places to assist in insertion or extraction.I'm having a senior moment I guess. What does PB or PB blaster refer to in several of the posts? Remember, blessed are the thick.
For those who elect to go the lower ball joint floor jack install method, I have found a simple 2-1/8" inside diameter exhaust coupler is a great tool. The 4" long coupler costs less than $3 at any parts store, fits tightly over the boot without cutting into in while sitting flush on the steel body of the joint. It is long enough that the joint pin will not protrude. If you plan to do this more than once you can invest in a heavier wall steel plumbing pipe with same 2-1/8" inside diameter for a couple extra dollars (I paid $6 at Lowes).
Put a little lube on the splines and boot then slide pin first into the coupler. Stand it on end on jack pan. Lift straight up into the control arm until the ball joint starts and the arm has lifted to about horizontal. Few hits with a mini sledge on the arm will seat the joint completely in less than a minute. Install your snap ring and zerk, slide off the coupler and thats it. No fighting with ridiculous clamp press or the short rings supplied with it.
I like the floor jack trick!
Is it absolutely necessary to remove the cv/axle nut when changing lower ball joints? And can they be loosened using a breaker bar and socket?
Think I have decided to wait on doing the lower ball joints until my I fix my air compressor and get an impact wrench to make the job go quicker and smoother than using manual tools. My uppers are shot. Boots ripped and dried out. The lowers look fine. The rubber boots aren't ripped or dried out. Plus this is my first time doing something this major with a limited set of tools, some of which I've had to buy just for this job. I'm certain that I'll have to throw more money into doing the lowers once I get into it.
I'm assuming when I go to do the lowers I will have to remove the uppers from the knuckle which is what I've already done now. I thought it would save me a step doing it all at once. But, I think I may have bitten off more than I can chew right now.
