how hard is it replace the pin in control arms? Can you just buy pins and replace the old one or is there a sleeve that needs to be replaced as well? If there a sleeve can it be honed out and an over sized pin the installed? HOw can you tell if the pins need to be replaced at all?

The bobtach pivot pins which have the a-taper end that fits into the end of the boom has a tendency to wobble out from the bolt which holds the pin in being loose , this will oblong(egg shape ) the hole the a-taper seats in , once this happens it is hard to kept the pin tight and it just keeps getting worse and worse , there is a bushing to fix this problem , easist way to install it is a magnet drill press , but can be done with a large drill , you drill the a-taper hole out so the new bushing can be placed in the hole , after assembling the bobtach and pins you weld the bushing in and the a-taper is back to OEM specs , Construction Tool Parts has the bushings , pins , etc ------if the weldment that holds the bobtach pin bushing in the bobtach has woddled out the hole there too much for a new bushing to hold in it , you can buy the weldment and cut , then weld the bushing holder in bring that bushing back to new
