S13 Rear Upper Control Arm Install

[positron1]

I finally got a set of rear upper control arms in. Here's the install!

Tools needed:Jack JackstandsCrescent wrenchSocket wrenchSocket extension3/4 socket11/16 socket3/4 wrenchBreaker barTorque wrenchSmall hammer

ProjectNissan RUCA'sThe RUCA's should have been the first rear mult-link suspension part I upgraded but I didn't...Whoops! Jack the car up and put the jackstands in the appropriate places.Next you'll need to get the breaker bar to bust loose the inner control arm nut.After you bust it loose, get an extension on your wrench and the 3/4 socket to remove the inner RUCA nut.Now get the breaker bar and the 11/16 socket for the outer RUCA bolt. You'll need to use the 3/4 wrench to hold steady the outer RUCA nut while you bust it with the breaker bar.Next, you'll need to remove the lower strut nut. Small hammerUsing the small hammer, gently tap out the inner RUCA eccentric bolt but before you do that you should stop and use a sharpie to mark the position that the eccentric washer was in before removal so you can put it back in the same position later.Eccentric bolt and washer.Now that you have the RUCA off you can slide it down the shaft of the strut assembly.Push the strut to the side and remove the RUCA.Take your new RUCA's and align them to the same length as the stock RUCA's.Use a crescent wrench to move the washers.Now you can put the new RUCA's into place, put your inner, outer RUCA and lower strut nut back into place. Use the crescent wrench to tighten the RUCA washers.Torque the inner RUCA bolts to 51-65 ft. lbs and the outer RUCA bolts to 57-72 ft. lbs. Replace the lower strut nut and torque to 57-72 ft. lbs.Finished! Hit up the alignment shop.

They are from Taiwanese company called TopSpeed. ProjectNissan and CourtesyNissan sell them. Used to work 1/2 mile away from TopSpeed.

Great write up. You've been quite helpful lately. How do you like the Megan racing stuff? I'm getting their T/C rods and RUCAs for my S13. What springs are you using with those AGX's?

The springs are Kilogram/Millimeter Supersports(KG/MM) and they're great! Before I bought those Megan parts I did a lot of reading and found out what people had to say about them. A lot of people knocked 'em but, on the other hand, a lot of people supported their products so I gave them a try and I have to say so far that I'm impressed.

Yeah, people knock Megan cause it's cheap. I don't care. The stuff is made pretty good and my car is not a race/drift car (although some people use their Megan stuff for this) so I'm sure for normal driving it will work just fine and be much better than stock. Plus with brands like Kazama, Cusco, JIC, Tanabe, etc. you are also paying for the name along with the part. I doubt they started out charging $300+ for RUCA. They make good stuff, but I seriously doubt their stuff is made that much better (read costs twice as much) than cheaper brands such as Megan.

I totally agree with you on those points.
