What did you do with your Z today V (ON TOPIC DISCUSSION ONLY)

Still battling this damn suspension creaking, rattling and clunking in the rear. So today, we cut some 0.25" heavy industrial rubber pads and installed them on the spring perches. Took it out for a spin, and... STILL RATTLING AND CLUNKING!!! Dammit! The creaking is pretty much gone though, so not a total loss I guess.

And yes, just as twice before, we have checked, double checked and triple checked all suspension points in the rear. Everything is torqued to spec, and checked again.

The only other thing I can think of it being is the top hats of the rear BC BR shocks being shot or the shocks themselves being shot. But as far as operation goes, the shocks are working fine and respond well to stiffness adjustments.

All I know is that this damn continuing noise is really starting to piss me off.

On a slightly brighter note, since the rear wheels were already off the car, we pulled the fronts off as well, thoroughly cleaned and scrubbed the backsides of them as well as the faces of them, remounted them, dried them and the tires, and then applied a healthy dose of Meguiar's #40 vinyl/rubber cleaner and conditioner. Made the tires look brand new again. Not that nasty, ugly shiny crap.

Oh, and lastly, I bumped up the stiffness slightly on the shocks front and rear. The fronts are set to 25 to stiff, the rears are 21 to stiff. Before, all four were at 15 (out of a total of 31).

ChopZ,
Is the differential bushing intact ?

I certainly hope so. The car just turned over 16k miles and is only 2.5 years old. I mean, I drive my car hard, but I don't spin the tires or make them hop. I would think that sort of recklessness would cause that particular bushing to go this soon.

However, with all of that being said, I honestly never even looked up there at it to see. I'll go out take a quick peek under there in a few. If I see a bunch of black puke running down the differential housing, I'll know it's shot.

I think there is a thread in the Brakes and Suspension section on rear axle clunk and how to fix it. That may be your issue. Mine has been clunking for a while and I am sure that is what it has to be as I have changed out every bushing possible in the rear suspension and I am running on true type coilovers.

Just took another look under the car a bit ago and the diff cover is spotless, so I'm pretty sure the diff bushing isn't shot or leaking.

I don't think that is my issue here. It only started immediately after installing the coilovers. There were zero noise issues before pulling into the shop to install the coilovers, but the noise issue was definitely there right after getting the car off the lift after the install.

And even after I took the car to the alignment shop to have the alignment done, he inspected everything and double checked the torque on everything as well for me. He even pulled the rear shocks, adjusted them and reinstalled them. Even he couldn't figure out what was causing the noise.

With all of the high end Porsche's, Lambo's, etc, etc and race cars he works on, I highly trust him with my car, which is exactly why I drive the 100 miles or so to have him do my alignments. He knows his shizz.

Right on, not questioning your shop, just proving information. Stranger things have happened.

Did you set the preload via the shock length? Example: you jack up the car under the spring perch, it should compress only 1/2 in. or so before it lifts the car of the jack stand it was sitting on. You only do this for the rear.

Nah, you're good. I wasn't think that at all.

Yup.

You did just fully read my post right above, right?..

Admired the lines under the cover.

NorthStyle · 12-17-2018, 07:50 AM

Cleaned up a bit of wiring and installed the new dash pieces to replace my previous headunit

ColtronZ · 12-17-2018, 09:24 AM

Really was not wanting to change my oil, but enjoyed it once I started. Kind of therapeutic. Plus I may have changed my oil 1k miles before my usual 5k. Oh well.

JARblue · 12-17-2018, 11:24 AM

Been thinking I should buy a CJ Motorsports billet top hat for my fuel pump assembly since mine broke last year. Just bought a used CJM Road Race Pump kit from a fellow forum member instead.

abm89 · 12-17-2018, 04:09 PM

I went to cars and coffee Sunday. Was the first time I drove the Z since buying a daily.

Also, Meguiars tire gel is very nice. Has the right amount of shine and my garage smells like berries.
