Lightbulb Light Racing UCA adjustment - pictures.

We installed the LR UCA yesterday ( Bulldog), and tried to set them to 0 as per http://www.toyota120.com/forum/showthread.php?t=12815

However the instructions where very basic. There are 2 adjustments that can be made - rotating the ball (the one mentioned in the instructions) and moving the entire assembly away or closer to the body.

Here is how we set them: all the way away from the body, and rotation set at 0.

Is that what everyone is doing as well?

Top:



Side:



Bulldog is an amazing UCA model



Here are some shots of stock and LR for comparison



EDIT: INSTALL VIDEO FROM SPC

Found this install video, would have been helpful yesterday
http://www.youtube.com/watch?v=ykEzU...ayer_embedded#

EDIT: Alignment done

So with the entire assembly moved all the way away from the body, and caster set at 0 on the UCA, the alignment shop was able to align to factory spec using the stock adjustments on the lower arm. Truck drives great, no noise, steering comparable to stock.

Here are the results:



EDIT
the top adjustment nut is 32mm, and needs to be torqued down to 120ft/p

Did you guys measure the tire clearance before & after the install? If so, how much extra clearance was gained? Andries, from your experience, how does the clearance fare with other UCA brands?

I would say the arms took about an hour to install, but we were doin th ecoilvers as well. It took soem time to figure out how to assemble and set these arms. Teh instructions for the arms is one of the worst I have seen. No instructions would have been just as good.

Teh arms does seem beefy and create more space for COs than the DR/Icon arms I have. Not sure about tire clearance since we are nto a 100% about the camber setting. Probably the same as most tube arms for tire clreanace.

Great pics. I'm still not clear on adjusting for camber / caster from that video.

Is everyone adjusting these at "0" and sliding the assembly all the way to the outboard side of the slot? I am installing these in a day or 2 and would like to do it right before taking it to the alignment shop.

I'm not sure my local shop will understand these Light Racing UCAs.

adjust them to 0 and when you take it to the shop, loosen the top nut so they can adjust the camber in the machine (thats per video, I haven't tried that yet, later in the week)

Thanks, so I'll set the locking plates like the pic below.

Then, tighten the UCAs up with the assembly towards the outboard side & then let the alignment shop mess with the camber by loosening the ball-joint nut. That gets re-torqued to 120 lbs when done, I think?

Please correct me if I am just a little too confused!

Yeah thats my plan. Right now my assembly is pushed all the way out, that makes camber off visibly, but I won't drive it much before adjusting it for good at the alignment shop this week.

Sandapanda & Bulldog -

Any chance of getting some equally great photos of the UCAs installed? That would be very much appreciated.

Also: were there any difficulties with removing either the driver's or passenger's side main UCA bolt? Any tips on getting these bolts out with the least headaches?

Lastly - I see that Toyota says the castle nuts which connect the ball joint to the spindle are non-reusable parts. Do these LR UCA's come with new castle nuts?

Thanks for all help, as usual!!

Igor can shoot some pics on his truck. Maybe even show off some pics of his truck with his awesome OW suspension

To remove the UCA bolts you will need a balljoitn puller. DOn't do it without using a balljoint puller. Also remove the ASB line from the UCA and make sure it stays clear of the UCA. I typically have the coilover removed when doing the arms, but you can probably do it with the CO in. Once the ABS line is clear, I use cable ties to secure the spindle from popping all over the palce. I normally tie the hole where the swaybar goes it to the top of the shock tower.

Tehn simply unblots the UCA bolts and pullt he balljoint with the puller.

Only reused the nuts so far.

Thanks Bulldog. Actually, I've heard that the problem with the long UCA bolt(s) is how long they are and that sliding them out - towards the front of the vehicle can be difficult.


In the video posted above, they actually say you may have to CUT the head of the bolt(s) off and use a new Toyota bolt brought into the UCA from the firewall side.

You don't need to remove the bolt all the way to get the arms in/out. You can slide them far enough forward to remove and install the arms.

We just pulled the battery and was able to pull the bolts out on both sides. Was kinda PITA, but with 2 people it wasn't bad at all. One holding the UCA and the other working the bolt. I did it by myself as well, and it was much more interesting then.

we took the bolt all the way out, had to remove the battery on driver's side, passenger's side no problem. Having two people helped a lot. I will take pictures tomorrow, today my wife took the truck to work and will return late :-(

Sandapanda - If you would be good enough to post your alignment shop results, that would also be very much appreciated.
