I have a CPP mini sub frame with tubular lower control arms and stock uppers on my 66 SS. Dropped spindles, stock springs. I did not use the ball joints from CPP, but opted for Napa Riebes upper and lower. My problem is I have ripped the upper dust boots twice (flexing somehow I guess) and Napa has agreed to give me another set of the boots out of a set. Has anyone experienced this? Everything is installed correctly and allignment is close. I want to fix this and get alligned.
Comments?

possible the spindle is coming in contact with the boots and is causing the tears/rips... check suspension travel or check spindle for tell tale contact evidence...

nice to know your local reputable parts house is taking care of you...

I believe this has been an ongoing issue on here with the CPP fronts. Do a search to see if I'm correct though.

I have a stock front end and mine tore also still not sure why so as soon as I get some cash saved up gonna do church boys lower when I have it apart to fix uppers

the lower CBR arms are fantastic... but check out the benefits with installing the uppers...

a lot of benefits to be had over stock uppers. :thumbsup:

Dust boots

Thanks for the comments - but I guess we still don't know why they rip. The suspension must travel beyond an acceptable range and rip the boot?

you'd be surprised how many members had boots get ripped just having their cars on jack stands with suspension at full drop. this is very possibly where the issue occurred... check your car and see. jack it up and take a look at it at full drop.

your suspension will never see full drop unless you're pulling the front wheels at the strip... or maybe if you're playing Dukes of Hazard and jumping rivers etc.

I agree and was going to post that earlier. Even without an engine or front dog house on the car they are at full extension maybe causing the issues.

The issue is the thickness of the spindle mounting boss for the ball joint. It is thicker than stock and creates a pinch point when the suspension moves.

Boots

I'm not in front of my car and can't picture exactly what that would look like. What is the solution? A diifferent boot profile or can the spindle or boss be fabbed to interface better?

Boots

When the front end is off the ground on jack stands - that is full extension and that will happen again when I change out the bbots next week. What if I put a block of wood or steel under the upper control arm where it rest against the frame. This would minimize the travel while I do the fix - just need to keep it safe.

The boot is not the issue nor the remedy. It is all within the design of the new spindle. Too much material in a place where it is not needed is pinching the boot.
