So my stock ball joints finally went after 90,000 km. That was with 33's. 35 are on order, have decided to get some aftermarket ball joints. Was thinking Synergy, but a lot of people in my Jeep Club do not have good things to say, and will not buy them again.
So what I'm asking is what do you guys run? What do you recommend? Poly? Alloy USA? Synergy? Teraflex? Dynatrac? Other?

 

I put in the Synergys about 20,000 miles ago; lube them at each 3,000 mile tire rotation. No problems with them yet.

 

The new TeraFlex BJ's look really promising, Dynatrac is way over priced! I have Synergy's installed but one does not accept grease. I went back and forth with Synergy on replacing it under warranty but got nowhere. I sure won't be going back to Synergy for any future purchases.

 

I have a BJ with the same issue. I put the jack user the vehicle and lift it an inch or two and the grease goes in with no issues.

 

I'm a fan of the synergy's. I've had mine for close to 20,000 miles and have no complaints. Fair priced, and have held up well with 37's. They even put up with the death wobble for a month before I had a chance to fix it.

 

I am at 42k miles on my 2012 JKU and am looking into ball joints. Always heard good things about MOOG, they do seem cheap at $25 a ball joint. I have no problem paying the Synergy price I just want quality ball joints. I may actually have to do adjustable joints.

 

I have less than 15k miles on my Synergy BJs running 37s and there already seems to be too
much play. I grease every 3k. I am not a fan.

 

geez, well the play in my OEM ball joint is very minimal, with ti jacked up and a pry bar under the tire you get a little movement up and down on one side (I think driver) I can see some daylight through it. The other side is fine. I am installing a Rock Krawler drag link as soon as it gets delivered. Then have it aligned see what the shop says about my joints.

 

You're talking about movement that's in the thousandths of an inch. 0.050" max to be exact. It'll be hard to see by eye.

 

I'm running the Alloy USA's and haven't had a problem with them (yet). It's been about 5K miles by now though so it's still fairly early to experience any kind of problems--- at least I hope.
