Reviews for Synergy Manufacturing Ball Joint Set for 99-18 Jeep Wrangler JK, Wrangler Unlimited JK & Grand Cherokee WJ

I used to sell these. Used them on previous rigs, one set has well over 100,000 miles of abuse.

Very happy with the quality.

They seem to be very good. Accessible grease fittings are a plus. As long as you have the proper tools installation was okay

well made product

Well worth the money!

Love it. Perfect fit. I do recommend it.

My order arrived on time and I received the correct product. These took the "death wobble" out of my 5in. lifted 2010 Unlimited Sahara JK with 315 70r17 Mickeys. It took a bit of time (it took me approximately 4 hours on the second wheel)(the first one took longer) but I installed them myself with a ball joint tool and YouTube tutorials. I have also noticed an improvement in handling over smaller bumps/gravel in roadways (possibly due to a tighter suspension now). I am very happy with the results.

Grease fittings not the easiest to get at without a needle grease end, but so far seem pretty tough

I don't know if its by design or I got a bad ball joint. I replaced my stock balls at 45K and now have 63K on the 2015 JK. The instructions say that these ball joints will be stiff for 500 Miles for me it was 10K. I have a 120 degree turn on a freeway I drive all the time and when these were new they were so stiff I could point the wheels in the turn at 70 MPH and take my hands off the wheel and the jeep would hold the turn. If these ball are not greased regularly like 2-3K miles the jeep will act like its wandering. Very strange feel. Considering Ball joints don't last long on jeep's and dodges I think I would rather have a good driving experience for 40K miles then 60K miles in these Balls. Defiantly looking forward to replacing these.

Terrible, First set installed lasted 6mo, thought it was a fluke put a second set in and only lasted about 8months.
