Steering pop/crack

[Aeterna]

So the other day i noticed what feels like a pop or crack (virbration) in the steering wheel you can slightly hear it when it happens.

It seems to mostly happen when taking a right turn and bringing the steering wheel back to zero. Or when taking a turn with some speed and weight shifts to the front driver side. So basically when the front driver side suspension gets some load it typically acts up.

The pop i feel in the wheel usually pops or cracks three times simultaneously. I check the front and rear sway bar and endlinks which look fine.


Anyone have any thoughts?

What year? Could be thrust washers on the hubs.There is a tsb for similar symptoms. Could also be a bad wheel bearing/hub.

Oh sorry that might help, its a 2013 with PP.

Thanks ill looks into those

To follow up on glock's analysis, there was the halfshaft issue/recall with the 2013s, yours MAY have been one of them. Bad issue to have happen, so best to be proactive. Check with VIN at

Just because they limit the date range for the recall doesn't mean your SHO does not have the issue.

 

[Aeterna]

Well it doesnt say i need the recall but maybe thats the problem. Ill try and find the tsb for it and check myself.

Awesome thanks

alright so, I found that the axle nut on the front driver side was finger loose. this is the big nut in the middle of the wheel assembly. I there was not a crush washer or anything with it, it seems to of had some sort of sealant or apoxy on the back side of the nut.

does anyone know if I scant re-use this nut and the torq specs for it? also if it needs a washer of sorts?

 

[Pintony]

Has anyone had this TSB done?

 

[glockcoma]

Hole-lee-**** !! Finger tight?!!
That thing should be something like 190 ft lbs.

 

[glockcoma]

There's usually some sort of cotter pin preventing the nut from turning that much

 

[Aeterna]

Alright so ive got it tightened down, but its still making the noise. Im looking for a thrust washer that is mentioned in the tsb glockcoma mentioned.

Anyideas where to get this thrust washer?

 

[glockcoma]

Thrust washer goes on the inside of the hub.
So you would have to put on the washer BEFORE you put the spindle into the hub. Then tighten the nut

 

[Aeterna]

Thanks yeah i sourced the thrust washer that will be in tomorrow.

Found a hub assembly locally that im going to install and see if it fixes the problem tonight.

thanks Shodded. Ive seen this but on my car the noise seems to be coming from the drivers side which I assume would be considered the left but the article mentions the right.

Ive got a CPO warranty on the car until 100k so i will probably reach out to a dealership for coverage if this thrust washer doesnt fix it.

 

[Aeterna]

it would seem that the thrust washer has fixed my issue, I will know for sure as I drive it more but so far so good.

thanks, everyone for the help. sucks that I fixed this only to put my car on Autotrader haha. I have my eye on a C7.

 

[SHOdded]

Too bad you are selling off the SHO

 

[Aeterna]

Yeah its bittersweet. Ive transitioned to driving my truck everyday so im wanting to get a coupe with a targa top as a weekend cruiser.

I messed up and rented a C7 when the GF and i were in Oahu now we both want one lol!
