Question about lower ball joint sizes
A while back I ordered a CLP-6370SWBK-6S from CPP for my 67 C10 and apparently the "6S" at the end means that the parts in this brake kit are actually cut for ball joints & tie rod ends for a 71-87.
I noticed that the ball joint taper is thinner, so then I ordered a CP4S9 spindle. This spindle has the original size ball joint taper. Problem is / my tubular control arms are also currently pressed in with the 71-87 ball joints. So now I have two options: * Purchase and press in 63-70 lower ball joints and use the original-size spindle * Use everything as-is and accept the thinner taper on the lower ball joint Option 2 is a ton less work, so my question is: should I be concerned at all moving to a smaller lower ball joint? Or just accept that my 67-70 has 71-87 front suspension and be happy that this new smaller ball joint is easier to source? Thank you! |

Re: Question about lower ball joint sizes
Are you using the 67 center link? If so then using the late model spindles means you will have to use an adapter to get the tie rod ends to connect. The link below will help explain.

Re: Question about lower ball joint sizes
Thanks @HO455, I still have the original 67-70 crossmember installed, so it sounds like from the post I can use either spindle I choose as long as I get the ball joints & tie rods to match the year of that spindle. Is that right?
Given that, which direction is preferred? Is there any benefit either way, or should I just stick with the smaller ball joints in the later-model spindle (which are already pressed into my control arms)? Thanks again! |

Re: Question about lower ball joint sizes
I know of no reason not to use the late model ball joints. It is likely that GM just realized that the part was over engineered and made it smaller. Plenty of square bodies around with no undeserved failures of the ball joints.
