TOTAL CHAOS UCA maintenance

Hello all, i'm fairly new to all this servicing on your own car but i've been trying to devour everything i can on this forum about my new fj. A couple months back i just bought my fj, and since i've put about 5,000 awesome miles on it. I read around and found out i had to grease my TC UCA's every 5,000 miles or so. I called the previous owner to ask when was the last time he had done it. He told me he hasn't done it in a very very long time. So i ordered a grease gun and some redline cv2 grease to grease the UCA's. I gave each zerk about 4 pumps of grease, i think i may have overgreased it.

a) does it matter that i use the redline cv2 grease, even if it's not the original grease that was put into the UCA's? If so should i take them apart and clean them out and regrease them?

b) is grease supposed to come out of the sides of the bushings so i know that it's been greased properly?

c) do these look overgreased (bulging)?

the black grease is the original grease that was on the uca's, i tried to wipe them clean so i could see if the new red grease would ooze out of the sides

Re: TOTAL CHAOS UCA maintenance

I dont think you did anything wrong. Maybe a little overgreased but no big deal. There is a pretty good YouTube video on TC UCA maintenance. Maybe you've already found it.

I usually just put a couple pumps in. Often times you can't even see the old grease push out initially. After about a week of driving is when I start to see the old grease come out. Just my experience.

Re: TOTAL CHAOS UCA maintenance

Most will loosen the hardware slightly prior to greasing. The washers do not allow for the new grease to expel the old.

Just a thought. I do not think you harmed anything.
Did you get any old grease out? Was there a great deal of pressure on the grease gun? Did you stop when you felt the resistance?

Re: TOTAL CHAOS UCA maintenance

i've never used a grease gun before this is the first, so compared to when i pumped the grease out without the fitting on yes there was pressure but it was consistent throughout the 4 pumps i gave each zerk.

and no noticable grease came out, i took it for a drive to see if any more grease would come out from it. should i try to loosen the bold the TC uca video recommends? or press on the ball in the zerk fitting to let out some pressure if there is excess? or just leave it as is and let it leak out naturally as i drive after a week or so?

Re: TOTAL CHAOS UCA maintenance

I would loosen the bolt and give a few more pumps.

If your hardware was tight and you got no grease out, or no resistance, then the bushings are not fully greased.

Re: TOTAL CHAOS UCA maintenance

Goes without saying but, you should wipe the zerk clean before greasing with synthetic grease which won't degrade the UCA bushings... As previously stated, loosen the UCA nut and bolt then grease 'em up and wipe the excess grease off that comes out and tighten things back up, 85 foot lbs or so on the UCA nut.

Re: TOTAL CHAOS UCA maintenance

Honestly the best things you can do is when you wash the FJ give the UCA a quick rinse to get rid of any grime/grit.

I finally gave mine a shot of Triflow for the first time in over 4 years. They have never made any noise in that time. I was greasing and lubing everything else to I figured why not them as well.

Re: TOTAL CHAOS UCA maintenance

It will be alright. You will get the feel of it. I use a dry lube on the uniballs too. I have used a few different dry lubes but I have an industrial teflon based aerosol at work that seems to last the longest. I lune the crap out of uniballs and rod ends.

Re: TOTAL CHAOS UCA maintenance

One more thing to add to all of the good advice you have gotten.... Another reason for loosening the factory through bolt before greasing is, if you don't, hydraulic pressure created by the grease gun can cause the urethane bushings to deform. This will ruin your bushings... Don't forget to re-torque the factory through bolt to 85 foot pounds...
