BMR Lower Control Arm (LCA) and Relocation Bracket Installation (w/pics)

TacoBill -> BMR Lower Control Arm (LCA) and Relocation Bracket Installation (w/pics) (11/13/2007 12:26:08 PM)
BMR Lower Control Arm (LCA) and Relocation Bracket Installation Install Time: 2 Hours Tools Required: Basic Metric tools, large wrenches (up to 22mm), torque wrench (up to 130 lb-ft) This install was performed on my buddy''s car, Leo06GT. See BMRs website for info as to what functions the LCA and Relo-Brackets serve. Tip by RUgoinUP Note: Be sure to do one LCA side at a time. Otherwise the LCA''s may not reach the relocation axle bracket upon re-installation. If you already removed both LCA''s, use a jack near the front of the axle housing (pumpkin) by the pinion flange, which will bring it close enough to work. Procedure: With the car on level ground, mark the rear shock relative to the protective outer sleeve. [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6915.jpg[/image] Loosen the lug nuts on the rear wheels. Jack up the rear of the car and support it with jack stands. Remove both rear wheels. Place floor jack under the rear axle housing and jack up the rear until the reference marks you made on the shock line up as if it were on the ground. This procedure replicates the car in static, level state. Also required to be in this position when torquing all the associated bolts. Starting with the Drivers side, remove the Parking Brake retaining clip. (Make sure the Parking Brake is disengaged) [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6906.jpg[/image] Unhook the cable end and route it out of the factory LCA.

Note: Clip nut stays attached to the frame, only the bolts gets removed.

Note: Use a rubber mallet if necessary to position the bracket.

[image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6942.jpg[/image] [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6944.jpg[/image] [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6940.jpg[/image] Grease both ends of LCA at this time (if equipped). Only 1 to 2 pumps are necessary, until a little squeeze out can be seen out from the bushing. Use the excess grease and rub it over the external bushing surface to make installation easier. Note: Orientate the grease fittings for easiest access for future lubing while on the vehicle. [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6957.jpg[/image] Be sure to orientate the LCA so the narrow end is forward and the offset in the rear is pointing inward (just like the factory LCA). Install forward mounting bolt, but do not tighten. [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6958.jpg[/image] Swing up the rear of the LCA into the Relo-Bracket. If it doesn''t align with the mounting hole, utilize a rubber mallet. If it''s really stuck, use a floor jack (if you have an extra one). [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6960.jpg[/image] [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/th_MVI_6962.jpg[/image] [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6963.jpg[/image] Note on which hole to use; If at stock ride height or up to an inch drop (like the Steeda Ultralites), use the TOP hole. If you have more of an aggressive drop, you may want to consider using the LOWER hole. Install rear mounting bolt through LCA and Relo-Bracket and tighten.

Note: Make sure the rear shock reference mark is at the correct position. Re-install Panhard Bar bolt cover. [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6950.jpg[/image] Re-attach Parking Brake cable and retaining clip. Tie wrap cable to side of LCA. Note: If cable end is slacked after installation, just cycle the Parking Brake handle and it''ll tighten up. [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6952.jpg[/image] [image]http://img.photobucket.com/albums/v673/tacobill35/Misc%20reference%20pics/Leo_LCA%20install/IMG_6953.jpg[/image] Repeat for Passenger side. Note: Some S197 builds have what appears to be a NVH metal block attached to the rear axle. Although not a problem on the Drivers side, it was an issue on the Passengers side. It would not allow the Relo-Bracket to sit flush up against the axle mounting location (see pic below). The decision was made to completely remove the blocks (both sides) to allow the installation of the Relo-Bracket. After an extended test drive, no NVH from the rear was detected.

LOL, I am planning on doing these this weekend and doing a write-up on it. I am installing the adjustable LCAs, reloaction brackets, adjustable panhard bar, panhard brace, CHE k-member brace w/ torque limiters, and BDI rotors (assuming I get the rotors and kmember on time). Now I have pics to help me through my install, Thanks!! [:D]

Great wrietup as usual, its like you read my mind I was thinking of doing LCAs too and now I definatly will thanks for the writeup!

drbobvs -> RE: BMR Lower Control Arm (LCA) and Relocation Bracket Installation (w/pics) (11/14/2007 6:27:21 AM)
Great instructions Bill. You should have done the Panhard bar while you were at it!

I was looking through the pictures and I'm like.. "What's that useless hunk of metal in your hand?" I don't think I have that on my car, never noticed it before.

Where's the TIP jar TB? Looks great!!!

JRT1 -> RE: BMR Lower Control Arm (LCA) and Relocation Bracket Installation (w/pics) (11/15/2007 12:38:20 PM)
I am curious about something. When you installed the relocation brackets wouldn't that make the length where the LCA fit longer? So how would you get the new LCA to fight right? I have adjustabled LCAs to install, so if I make them the same length as the orginals how do you fight them in place? The NVH noise blocks that you removed, how do you know that is what they are for? I haven't looks to see if my car has them, I am planning on doing some of this work this weekend and I am wondering about any adverse effects from removing them.

Good write up!

Nice writeup, although I did mine a week or so back! Quick question: where did you find guidance on using the upper or lower hole in the LCA relocation bracket? You state "Note on which hole to use; If at stock ride height or up to an inch drop (like the Steeda Ultralites), use the TOP hole. If you have more of an aggressive drop, you may want to consider using the LOWER hole. " I have the Steeda springs with 1" drop, but used the lower hole of the LCA. What's the downside, if any? John

Awesome, Should have got it in RED [image]local://upfiles/19878/C1B520AAEB2743F38AE410E25D73F74F.jpg[/image]

drbobvs -> RE: BMR Lower Control Arm (LCA) and Relocation Bracket Installation (w/pics) (11/15/2007 1:45:05 PM)
No problem using the lower hole. You MAY notice a harsher ride when accelerating but most likely you won't. Using the lower hole will give you slightly more traction upon acceleration.

DeStonn -> RE: BMR Lower Control Arm (LCA) and Relocation Bracket Installation (w/pics) (11/15/2007 2:01:14 PM)
I keep offering my car and car parts for Bill to install so he can do more write-ups. [:D]

Great write up the Parking Brake retaining clip was a pain in the ass to replace for some reason
