just like the title says. installed some lca relocation brackets friday night, everything was fine and dandy. tonight i switched them to the lower hole just to try it out. went out to test it and clu clunk clunkity clunk clunk squeak clunk.

i lurk these forums 24/7 and have never heard of this happening.

why is it happening on the lowest hole and not at the middle?

i'm guessing an adjustable phb will fix it?

When you had them in the middle hole were the control arms level, higher in the front, or lower in th front?

almost perfectly level. about 1/4" lower in the front.

Shouldn't be touching your phb unless your lcas are out of square or your t/a is allowing the axle to be pitched down too far which would cause more problems.

but if it is one of those why would it matter whether they're in the top hole or the bottom hole?

"why is it happening on the lowest hole and not at the middle?"

As the axle moves up/down it also moves from front to back to front again ; in a arc like this: ( .

So when it's in the middle hole as the suspension compresses the axle is moving forward, but when it's in the bottom hole the axle is moving back as the suspension compresses.
Do you have a 9" ford, or 12bolt chevy rearend, or stock?
Adjustable LCA or stock?

stock rear and lca's

thought it was more of a right to left thing causing it than a front or back, i guess that makes sense. if it's front to back though then is a panhard bar gonna fix it?

Hello, did you get the lca's torqued down properly? Who's lower brackets are you using?

therealcreeper

iTrader: (37)

torqued the lca's to about 90 lbs if i remember correctly.

i ordered RPM speed brackets but the hardware/instructions i received were from UMI. brackets aren't labeled so i really don't know who's they are hahah.

One of 2 scenarios :

• The brackets are not made correctly
• The brackets where not installed correctly

If you could possibly take a picture of the brackets installed maybe we can figure this out

If you can, post some pictures.

here's the brackets-dont think it's possible to install them wrong


here's where it's hitting. the upper arrow is pointing to the "upper phb"
you can see my sweet duct tape job with the hose underneath.
the lower arrow is pointing to where it hits the spring, where the tape is.

and yes i need new bumpstops

i set them back to the middle holes tonight and have about 1/8th inch of clearance now.

It's nowhere near the panhard bar, so no.
Can you move the lca to each hole without moving bracket/housing?
Are those aftermarket lowering springs? Are they larger diameter than stock?

well if the rear is offset towards the passenger side of the car now, and the bar then pushed it left, wouldn't it move the spring away from it slightly?

to switch holes i just drop the whole arm out. haven't tried without but i don't really think i could.

and these are slp eibachs in the rear. never thought of that. they came stock on some SS's and firehawks with the level 2(i believe) suspension package so i'd imagine it's not because of the springs.

i'm not entirely sure which way the axle is shifted. when the car is jacked up and weight is taken off the rear the driver's side hangs a few inches lower.

Do you have a Adjustible T.A., or factory T.A.?
Have you checked the condition of the front TA mount and bushing(loose, broken, bushing wornout)?
Are you LCA bushing in good shape?

I'll post later after I look under my car, for a possible solution.

stock TA haven't really checked it out at all. i noticed today that while in the lowest hole my wheels sit really far back in the wheel wells. i ordered a new phb since i need one anyways so when i install that i think i'm gonna see if i can get the brackets to move forward at all. they may just be made wrong as they're from a newer company.

could be an installation error but they're pretty far off.

So everythings fine with your Torque Arm mount, and bushing ? Maybe it is your relocation brackets?
My suspension's all aftermarket. I also have bolt in relocation brackets (BMR)on the lower hole, but I have air springs, not coil springs and also my wheels are centered in the wheelwells (front to back).
So here's some pictures I took of mine and maybe that will help you figure things out.

When I compare your photos with mine it really looks like your lower mount hole is too far forward!

thanks for all the help man. the angle of the picture does make it look pretty far forward, which i guess would cause it to push the axle back. would it be super obvious if there was something wrong with the torque arm bushing/mount?
