Lower control arms touching front disks

[babybashjnr]

I put my car up on the hoist at work and saw on the disks there is a point where the lower control arms actually touching the inside of the disks. It only touches when steering is on full lock
The civic had 16x8 +20 rims on before and had an aggressive camber setting
I have now changed rims to a 15x7, raised the height a little and sent it in for a wheel alignment. This was done about 2 months ago

It's a ek4 with BC coilovers, buddyclub extended ball joints, buddyclub adjustable upper controll arms and nothalened bushes

Any help would be greatly appreciated

Grab a angle grinder and massage off the outer part of the knuckle that touches.

I think he's saying the Brake Disc (or dust shield) touches the LCA, not the knuckle..

Possible causes:

- Faulty ball joint (has play)

- Bent LCA

- Bent Knuckle.. unlikely

- Rotor too thick.. unlikely


Can you take a picture of where its rubbing

[babybashjnr]

I will take a picture tonight. But yeah the dust shield is in between the lower control arm and the disk, the disk is actually rubbing on the LCA and u can see the point that its touching on because its perfectly circular on the disk

Also I noticed that the nut on the top of the ball joint doesn't go all the way down the thread on the ball joint but it has still got the lock pin in it (I will take a picture of this too)

Could it be that the extended ball joints weren't installed properly?

Would switching back to standard ball joints fix the problem?

Thanks

It's rubbing almost in the centre of the disk. And yeah it is the nuckle that is touching

I've seen this before - with excessive lowering and or larger brakes ( such as a 5 stud conversion)

how the hell could the knuckle be touching brake discs?
you sure its not the ball joint nut/lca?

im just thinking its impossible for disc to touch knuckle unless using incorrect hat height

Possible - OP look at the crown nut and see if its notably rubbing or showing signs of rubbing

Mind the grease everywhere from the split cv boot

Is it possible that the guys that did the wheel alignment didn't adjust the upper control arms? Or would adjusting the upper control arms change the angle where it is touching?

[mocchi]

thats the lca not knuckle
check for worn bushes
how low is the car?
shocks bottomed out?
previous accident? could be bent knuckle

need previous history before all this happened.

Are you running bigger brakes / thicker rotors by any chance?

The problem is definitely amplified with the BuddyClub RCA's but I don't know if it's the main cause

Have a read here, lots of ideas and opinions:

Bushes are fine they are near new and have been nothalened
The nut is pretty badly worn down, I am currently uploading pictures of the nut to my photo bucket account and will post them up shortly

I bought the car with all the current mods on it
Here are the suspension mods
Suspension


Project Mu Type NS brake pads (Front & Rear) Just changed 1000km ago
282mm 4×100 MPR Custom Rotors
ITR Calipers
Innovative Shifter Bush
BC-BR adjustable Coilovers
Skunk2 Front Camber Kit
Hardrace Rear Camber Kit
MPR Rear LCA's
22mm Rear Sway Bar
ASR Brace
C-Pillar Brace
Front Strut Brace
Replaced OEM and Nolathane Bushes through-out
Buddy Club "extended ball joint" replaced when suspensions were changed in March 2012.

This is my theory...

When you install ITR calipers onto EK hubs (or any 262mm hubs) you need to shave the caliper down by 3mm so it lines up with the rotor.
That means the rotor sits 3mm closer to the LCA (EK 4x100 hubs and ITR hubs have different offset)

So your rotor is now sitting 3mm closer to the LCA PLUS you have the BuddyClub RCA which just makes it worse because it lowers the plane of the LCA giving less clearance to the rotor.

On top of all that, you have custom rotors, so it's possible the hat offset of the rotor is off by a bit..

get new drive shaft's those are ****ed lol

[babybashjnr]

So maybe just get some ITR hubs?
I had an eg4 in nz that had the 4x114 hubs and the ITR brakes (changed to prelude calipers later) and had no clearance issues even on the track

[babybashjnr]

Hahaha yeah man I'm still trying find another set so I can have these reconditioned and keep as a spare set
It's also because of the split cv boot I actually found this problem:/
