Hopefully that will get corrected as well.

bringing this back from the dead -

I have very loud "groaning" or "croaking" from the rear. Is this a result of that as well?

Your signature doesn't say what type of springs you have. Not sure if what you're hearing is due to the equipment you chose or not. Timing or recocking the bushings wouldn't cause the noise that you hear, I wouldn't think.

I had Eibach Pro Kit on my previous Camaro, a 1LT/RS V6 and I had a noise in the rear as well but not all the time. My springs had rubber covers on them in areas to reduce any noise I know. I think my issue was the springs coming out of perch in the rear. It always happened and I got a hold of Eibach who gave me my money back and I ended up going with Pedder's and no more issues or noise. Now that I have a newer SS and couldn't get Pedder's I opted for Detroit Speed Engineering and love them! No noise what so ever and the ride is impeccable, the stance is perfect!

The timing of the bushings should be done anytime the cars ride height has been altered either by lowering or raising. This helps the car to have a smoother ride in my opinion as the bushings had been set to the factory height and equipment. Timing basically re-establishes the bushings to the new gear and height.

Thanks for your response!

I have pfadt 1.25" springs installed.

It's like a groaning or a croaking...

Will it ever go away? They do have some rubber Isolators on them as well but I can't determine what would cause this.

So you don't think retiming or clocking bushings will do anything?

What could it be then?

Anyone know of an alignment shop in San Diego (preferably north county) where I can get this done? Do most alignment shop techs know how to do this? I don't want to go to a shop that says they can do it only to find out it's the techs first time attempting to do it. Thanks

Print this post and take it with you. Show the shop manager the instructions and alignment specs. With the instructions most any shop will be able to do the work.


Bush Timing, Alignment and Torque Specs


Do NOT use camber adjusting offset bolts on the Camaro



If you want to put them on your Honda or Subie it is up to you. They are not as strong as the OEM clevis bolts and are absolutely necessary on a 5th Gen Camaro. It is in the

This is the correct way to adjust front camber on the 5th Gen. One the alignment machine with the clevis bolts loose turning the camber screw tighter (Righty Tighty, Lefty Loosy) will push the knuckle away from the strut. Loosening the camber screw allows the knuckle to fall in toward the strut. It is a 10mm 1.5 pitch thread.



Your alignment shop may have a T.O.M.C.A.T. Air-Assisted Multiple Camber Adjustment Tool air bag. It fits between the wheel and the strut and works in the same way as the camber screw. Inflate (Righty Tighty) the bag to push the knuckle away from the strut or deflate (lefty Loosy) the bag to allow the knuckle to fall into the strut. If they don't, they have a guy that can push or pull on the wheel while they tighten it. Never, ever use those lame camber eccentric bolts on a Camaro. EVER!



Anyone that tells you different, have them call me

Pedders foundation as a company is more than just a range of bits, we are Suspension specialists committed to delivering a Pedders Driving Experience. A lowered vehicle should have a full range of alignment adjustments. The Camaro delivers from Chevrolet with a fixed Castor position. The radius arm bolts into round holes with no available adjustment. Front Camber is adjustable from the factory. There is a threaded hole for front Camber Adjustment Bolt / Screw, but no bolt is installed and no part number is listed by Chevrolet. The rear OEM eccentric adjusters for Toe and Camber provide approximately one degree adjustment range. For an alignment specialist, this is unacceptable. You want to get your Camaro perfectly setup. This is what Pedders is all about. Our solution is a set of cadmium plated eXtreme Alignment Bolts. While GM made the hole round for the front Castor Adjustment or lack thereof, they did weld in brackets for an eccentric to work against. Your local Pedders Dealer can create a slot to provide Castor adjustment with Pedders Camaro Alignment Bolts. The kit provides the front Camber screws that GM didn't.



For the 5th Camaro, GM decided to produce the front sub-frame with only a round hole, but they kept the 'fences' for caster adjustment with eccentric bolts just like th Pontiac G8 and Holden Commodore. The slots to allow adjustment were lost in translation. For a performance driver, a vehicle without full alignment adjustment capability feels like driving with one hand tied behind your back. Pedders made the decision to make the Camaro front suspension fully adjustable.

Stock Radius Bush Mounting area with a round hole and adjustment 'fences'.



Step one requires the technician to drill two holes in the bracket.



Step two requires CAREFUL GRINDING. We use the two holes to make the grinding process more accurate while the technician creates a slot. The eccentric that will be used does not reach all the way to the bracket sides so a bit of excess metal is not an issue. The technician can check the clearance with a Pedders Castor Eccentric Bolt as they grind to make sure the fit is Pedders Perfect.



When assembled the Cadmium plated eccentric allows the alignment technician to increase or decrease Castor. A fully Pedderised Camaro with good tires will not require ANY BIAS in the alignment. We can do a road course style alignment and your Camaro will not pull. This is because the Pedders component have made the suspension more stable by reducing excess motion. Should your Camaro be tweaked and develop a pull the same Pedders Castor Eccentric Bolts can be used to create a bias to correct the pull. We strongly recommend that before you alter your alignment due to a pull that you have a qualified technician, because the machine is only as good as the tech, check your tires on a road force balance machine to make certain the pull is not induced by a tire. We will adjust them on the alignment rack. Here is the installed eccentric.



Alignments are Pedders core business so we decided to make the front camber screw part of the Camaro Alignment Bolt Kit. To install the Pedders Front Camber Screw it is essential that you use LocTite Blue. The Camber screw will never bear a load while driving, but we want to make certain they never vibrate out. LocTite Blue is ideal for this.



Pedders Rear Eccentrics are virtually bullet proof with approximately 2 degrees or double the factory adjustment. With the Camaro alignment Kit installed your Camaro can be setup for the drag strip, road course, auto cross or every day flawless driving. Even better, Pedders alignment eccentric bolts carry a unique warranty feature. Should a Pedders eccentric ever fail while you own the vehicle we will replace it. You get a superior alignment, improved driving experience and a life time warranty with Pedders Camaro Alignment Bolt kits.

To get the aggressive alignment we prefer Pedders Full Camaro Alignment Kit is required. They increase the adjustment range by 1 degree or in layman's terms a lot. We achieve this result my moving the eccentric to the outer edge of the bolt. The eccentrics are cut on a water jet, assembled in a jig and welded. This is a time consuming process. To finish the bolts we have them cadmium plated.



Eccentrics have a bad habit of drifting under high loads. We address that with more material. We make our eccentrics out of stock that is much thicker than the OEM bolts. More material means more strength and improved holding power.



We use a thick 'holding' nut and a thin jam nut. Unlike quenched nuts, you can use these again and again.



Taking the performance of your 5th Gen and alignment to the next level requires the use of Pedders Dual Bearing Camber Plates. With the stock front struts or Pedders coilovers you can achieve -2.2 Degrees of front camber. Relieving the upper slot in the strut to allow it to fall in a bit more will get you to -2.5. When running high negative camber it is Mission Critical to check spacing between the inner tire sidewall and the strut or coilover. We use a standard #2 lead pencil as a gauge. If the pencil passes between the tire and the strut or coilover you are good to go. With Pedders Dual Bearing Camber Plates we suggest you run them full in, maxed out for negative camber. Positioning the stut top well in toward the engine improves SAI. Your 5th Gen will drive better. Final adjust the negative camber at the knuckle using the camber adjustment screw.

Maxed out for Negative Camber



Neutral Position i.e. The same position as the OEM Mount.



FE4 / FE5 / ZL1 / Pedderised Hardcore Track Alignment with Appropriate Tires

Front
Caster: Max it out with Pedders Caster Eccentrics
Camber: -3.5 With Pedders Dual Bearing Camber Plates and NO Strut Tower Bar.
Camber : -4.00 With Pedders Dual Bearing Camber Plates and a Strut Tower Bar
Toe: OUT 0.50
Total Toe OUT 1.00

Rear
Camber -0.80
Toe: IN .20

Pedders Full Camaro Alignment Kit and Dual Bearing Cambers Plates are Required.

Bush Timing

Step 1. Lift the car on a two post lift and raise it.

Step 2. Loosen the following bolts/nuts:
Front:
---Inner Control Arm Bushing
---Inner Radius Rod
Rear:
---Trailing Arm Bushings (both ends)
---Toe Rod Bushings (both ends)
---Lower Control Arm Bushings (Inner)
---Upper Control Arm Bushings (Rearward)
---Lower Strut Bushings

Step 3.
Lower the car and drive it around the parking lot SLOWLY and on to the alignment lift.

Step 4.
With the weight of the car on the wheels tighten all of the nuts/bolts to spec.

Step 5.
Align the car at the new ride height.

Alignment




Front and Rear Bolt Torque Values




NOTE: Torque specifications that read XX torque value and XX degrees are usually TTY and require replacement of the bolt, nut or both. If replacement parts are not available from GM the minimum acceptable torque will be those values stated along with a liberal application of a thread locker i.e. LocTite.

Subscribing to this so hard. I'll be replacing my sway bars and toe rods soon, and I wouldn't have thought about timing the bushings on the toe rods. I'll keep this in mind when I eventually get coilovers too.
