I've had my AS 2" leveling kit on for about 4 years now. About a year after install I swapped out UCA's for MOOG's, and they are now toast. Have about 3 years and 30k miles on them. Kind of expected more life since I only have a 2" level, but they are sloppy and noisy now. I might not have greased them as often as I should, but not sure.

Is there a better option to put the ball joint at a less severe angle? Or do I just get another set of the MOOGs and expect to get another ~3 years out of them?

 

You can get mood again and grease them regularly and you should get more life. If you think you won't grease them as much as it should be done, the upper ball joints without grease fittings may last longer.

Other options would include jumping up to an uniball upper control arm like the camburg or total chaos one but the price difference from those to the moog is pretty high.

 

What's the recommended interval for greasing them?

 

I've been running a 3" lift since day one. Changed the factory UCA's at 60K and have been going strong ever since with the MOOG's. Just went over 125K.
I grease mine at every 5K oil change.
Your mileage may vary.

 

I check mine every oil change and add grease if needed.

 

Moog told me via phone to add one squirt of grease every oil change. They get just that every 3k.

You can feel the rubber and know if they need some grease or not.
