Oversized balljoints?

[fr0st m0nkey]

Just saw on RockAuto that they make "oversized ball joints" and ball joints specifically for the explorers that came with 17" wheels. Would either of those be better than stock for use with a 1.75/front 1.5/rear coil spacer lift?

Just looked at those...looks like both Moog and Mevotech make them. At that price it can't hurt, as long as they fit your control arms.

Beefier balljoints will not solve the problem. The upper control arm is the problem. Go back and look at the picture of the failure and notice that the balljoint is still intact and the upper control arm is ripped out. The angle of the balljoint after installing the spacers increases so much that it "bottoms out" against the side of itself and rips it out of the control arm. You could have the strongest balljoint in the world and it would still do the same thing. The only true fix would be to get the BTF upper control arms. They are longer to get the camber adjustment back and the angle of the balljoint mount is corrected to match the new angle so the balljoint doesnt bottom out on itself. They are also beeefier around the balljoint. This is the only way to fix the problem.
I just dont want people thinking they can put new ball joints in a add the spacers and they will be good to go and they ride will be safe because its wont be. The control arm where the balljoint mounts is the weak link.

If someone can post the picture I mentioned above they can see where the problem really is. This will be the same case in any of the failures. I have never seen a balljoint come apart or fail in that way only get loose and floppy.

Also want to mention the wheel spacers that everyone uses add sooo much more leverage(more than you can imagine) to the upper balljoints and contributes to this problem in a big way also as well as the added stress to the rest of the parts.

Just my 2 cents.

Post up the CAD files for your drop down brackets so I can avoid having to buy BTF's control arms!

Would beefing up the stock control arms and adding 'oversized' balljoints help? I just did some googling for stuff about strengthening stock control arms and it looks like it's been done. You seem to know a lot about this stuff, drop some more knowledge on us.

Also, I developed some 1.75 front/1.5 rear coil spacers in Solidworks 2012 that I'll post up here if anyone wants to make their own.

this one?


the guy was running a 3" coil spacer and a 2" wheel spacer

Not going to post the CADD files of the brackets of. I have months of hardwork creating them.


Yes, Beefing up the control arms would help but there are not many ways to do it. If you have all of the tools build you a set....

Shucks

I've got a full ag engineering shop at my disposal this quarter for a fabrication class I'm taking, I'm sure one of the professors will know how to strengthen them. Spacers and a body lift it is.

I uploaded the spacers I made to grabcad if anyone wants to check them out or make their own.

Not sure if I am going to have time to finish getting this stuff into production I have been really busy with work and other stuff lately and had to put this on the back burner.

I may be willing to sell all of the details and CAD and DXF files to someone for $5500 who may want to take it the rest of the way. I have everything deatail in AutoCad for all of the parts and materials. I also have Nested DXF files for the Laser cutout of all of the flat peices. Enough to be able to send them to a vendor to have made.
