If you have an aftermarket lift kit with adjustable control arms, chance's are great you have Curries Johnny Joints on at least one end. These Joint's are proven tough and durable being among the best on the market. Many companies use these Joint's because of that fact. These Johnny Joints have bushings that do however eventually need to be serviced.
Being the freak that I am about maintaining my JK Wrangler I took some time to change out the bushing on a 2" Johnny Joint and I thought I'd share the process with you.
Here's what I'm working with. Upper Currie Control Arm, frame side.
It's not unusual for dirt and grease to collect, so is good to pull these at least once a year to clean them up. For this, I use WD40 sprayed onto a rag. It does a great job cutting through the collected junk, and it's not a anti grease agent.
Having need to changing a bushing in the past, and after two hours, failing horribly using the socket/vise approach I finally gave up. Little did I know the local shop charged me $20 bucks to change it out.
Doing some research I quickly found out, not only does Currie make a outstanding product, they also provide means for the DIY customer to change these for themselves.
I purchased the 2" and the 2.5" tool to do these myself. Here's the 2" tool:
Setting it up in the vise:
The way the tool works is by compressing the bushing enabling easy removal of the retainer clip. So inserting the all thread through the bolt hole and placing the compressing nut on the other side, begin tightening.
As you can see in the prior pic and the next one, you need to compress the bushing by tightening the nut with a wrench, loosening just enough to have access to the clip.
With proper snap ring pliers, collapse the clip take it out. It should come out unhindered.
A pic of the retainer clip:
Once the clip is remove flip the Joint over and remove the internals in the same direction from which the clip was removed. It may take some convincing. A socket and a dead blow hammer worked for me.
Here is what the insides of the Johnny Joint looks like:
It goes without saying, clean things up, inspect the ball, clean the barrel and the groove where the clip sits.
These are the new bushings we are replacing the old ones with.
If you notice, these are grooved to mate together. It is very important they are mated during install.
Install is simply reversing these steps. A few notes and I do apologize for not getting pics but my hands were covered with grease at this point.:crazyeyes:
A few pointers though,
First, be sure to clean everything well. washers, clip, ball, and barrel including the hole through it.
Second, It would be prudent of you to lube the barrel, ball, and bushing with fresh grease as you piece it together.
Third, remember the order in which the pieces came out.
Washer, bushing half, ball, second bushing half, second washer, clip, is the right order of install.
Fourth, clean the groove before reinstalling the clip.
Fifth, grease the Joint once it's installed back on the JK. Be sure not to over grease the Joint.
These are pics of the old bushing.
A little wear, but not excessive:
And you can see how they mate together:
I sure do hope this helps you out. It is cost effective to have these tools made by Currie not only to save you labor costs, but to help out a fellow Jeeper.
I ran these bushings for just under 20,000 miles with some serious wheeling.
The bushing are about $10 bucks.
I am a freak about preventive maintenance, so I am more apt to chance these out before there time.
Pics aren't the best, they are from my Iphone.
Good luck, and keep your balls lubed, and you nuts torqued.:thumbsup:
