I'm looking for some help on how to remove the shakle bushings out of the wish bone and rear end. I tried pentetrating spray then heat on them and they will not move. Do I need to get the metal red hot? I have the same problem with one axle bolt. I have a new shakle kit w/ springs to install Any help would be appreciated! Figs48

I pressed mine out. I did have the entire rear end assembly off of the car though. Once the cotter pin and castle nut is removed from the shackle stud you can knock the spring off the stud. Just be aware that the spring will snap rapidly inward. I have not replaced any with the assembly still on the car.

As you may have suspected there are specialty tools for removing and installing these shackle bolt/bushing assemblies. If you don;t have access to them you can still removed the old ones fairly easy. I would suggest you first knock the center pin out of the bushing. Then, using a punch that you have ground a small curved edge in to simply catch an edge of the old outer bushing (metal) and begin to hammer / peel it away for the perch. I've done too many to recall this way prior to obtaining the specialty tools. This method works with relative ease. To install new bushing/pin assembly is another story... To do this correctly the specialty tool is a near must. The reason being the proper new bushing / pin will be about .003" to .004" oversize and must be pressed in to the perch. Attempting to pound it in will only mushroom the outer metal sheath. Grinding the new sheath down to a matching size simply defeats the purpose of replacement. These pins MUST have an interference fit in order to work as designed. Think "torsional twist". A lot of fellows will tell you they've been grinding them down and have been fine for years. Well yes, they have. Have they done the job correctly? No way. Simply stated... why replace a worn bushing with a new (ground down = worn) bushing?

I tied using a punch on one bushing and all it did is mushroom the bushing inside the housing- now what? Drill out? If so what size drill bit so I don't oversize the hole. Thanks for your replys! Fig

I have had luck with an air chisel and a small muffler bit to slice the outer sleeve after removing the center. You will have to grind the "wings" on the bit back, and grind a convex radius to match the bore, but the bit will roll the sleeve in enough to break it away from the housing. Sooner or later though, you will have to buy, borrow, or make a proper tool to insert the new bushing assy. without destroying it.

as stated before, drive the center pin out, then take a hacksaw blade and feed thru the hole. Carefully cut thru the bushing outer sh*ll--do not cut into spring--bushing will now drive out a small chisel. When this has been done, to install a new bushing first hone out the spring eye until it is very clean and smooth-no rough edges. You can then use a big c-clamp and a few home made adapters and puch the new schackle pins back in the spring. I use a couple of home made pipe adapters--one to fit the outer diameter of the spring eye (leave enough space for the pin to push thru) and another to fit the bushing sch*ll, leaving enough space again for the pin. I use a rather large c-clamp probable 10" gives enough strength to do this with ease. Be sure the outer sch*ll of the new bushing is smooth, use a very little light oil and go for it.
