Uca lca installation

Hey guys I need to get my upper control arm and bracket(hotchkis) (bmr bracket) and bmr lcas w bmr relocation bracket installed. I'm lowered on the eibach pro kit. Should I get the dealership to install that stuff or could I do it? My dad has any tool I would need. But idk how to do the pinion angle. I need y'all's opinions or recommendations.

Uca lca installation

First off I'm not completely sure why your UCA and bracket are different brands, they are made to work together and some are not compatible with a different brand.

Aside from that it is not difficult work to do from an intelligence standpoint but it can be physically demanding and exhausting. My main concern would be getting the new Uca and mount in and properly tightened. That actually holds the axle to the body.

If you decide to do it yourself, plan for a minimum of 6 hours of work time. With the proper tools, knowledge, and strength it's a moderately easy task.

I don't remember which hole the uca should be mounted in on the bracket but I think it's the lower hole and for a street car I would mount the lcas into the middle hole on the relocation brackets.

Most shops that can do alignments should be able to adjust pinion angle so long as the have an angle finder. That cannot be done on jack stands very easily

They may not "have" to match. However, it's just a good rule of thumb to match brackets with parts of the same brand to ensure the best fit and compatibility.

There's several videos you can watch, like the CJ pony parts one that shows how to install them.

The LCAS aren't bad, but the UCA takes some convincing.

I can do the lcas I'm sure but not the uppers. I guess I should let the shop do it. Will ford know what the pinion angle should be now?

Uppers? Plural? Just making sure you only bought 1....

Ford would, but the dealership is generally the most expensive and worst option. They normally don't stand behind their work with aftermarket parts and are 2-3 times more expensive.

All good. Forgot to mention, a shop that does suspension can look up the pinion angle. They almost all use Alldata which has factory specs for most cars on there.

On a street car you will want it somewhere between 1.5-2*

Per BMR instructions
ADJUSTING PINION ANGLE WITH AN ADJUSTABLE UPPER CONTROL ARM
Make sure the rear end is loaded by either setting the car on the ground or letting the car rest on jack stands positioned under the rear axle. In both cases, the car needs to be as level as possible and the suspension loaded.
• Place an angle finder on the rear portion of the two piece driveshaft and record the angle. Now place the angle finder on the pinion yoke and record the angle.
• Subtracting one angle from the other results in your pinion angle (Example: -2 rear end angle subtracted from 0 driveshaft angle = -2 degrees)
• Adjust the control arm to achieve the desired angle.
• As a starting point, most cars respond well to the following initial settings: Automatics: 1-2 degrees negative, Manuals: 2-3 degrees negative
• Once pinion angle has been set, apply Loctite to jam nuts and tighten.

If your doing it on the ground make sure you can torque a bolt to 130-ft lbs while on your back

Have a good 1/2" torque wrench and get the car in the air as high as you can. Certain parts of the LCA / brackets need to be tightened to like 130 ft/lbs and that is a ***** if you're cramped under the car. All in all i agree with others, its not a "difficult" install, its just physically demanding since all that **** is so tight.
