PTU Failing??

[sub_ETCS_ret]

I'm getting a weird noise from the front right side of the car. It's mainly when the car is cold and turning left under acceleration. It sounds like a clicking or something slapping the firewall from the front right side by the passenger's feet. When the wheel gets straightened it stops.

Right-Half shaft maybe! Check Trans fluid level ASAP!  Z

Either the halfshaft as per the 2013 recall, or the strut mount/bearing are most likely.  Tie rods sometimes fail.  Far less frequently control arms/swaybar links.  So halfshaft/CV joint and strut mount would be my gotos.

Thanks! I was thinking half shaft.

Are you talking PTU fluid or transmission?

Trans fluid level.  Does not seem like a PTU problem at all.  Much more likely to be a hub/bearing problem or halfshaft problem.

Appreciate it.

Why would it only make the noise when it's Cold? Seems like if it were a wheel bearing or half shaft it would make the noise all the time.

Looking for a video or instructions on replacing the half shaft. Is it easy on this car?

How many miles on your SHO!
The Half Shaft recall is usually a visual inspection IIRC!
Here's a video that should give you some insight.  Z

Fluids are thicker when cold and do not flow as easily.  This means less lubrication for components, and more likelihood of improper engagement or metal-to-metal contact.

Same goes for hard parts - due to expansion and contraction, gaps may go out of spec when cold, but be in spec when warmed up.

This is not even accounting for the presence of actual wear, which exacerbates the issues at hand.

Lol. I think you attached the wrong video.

So even though I have a 2015 you think the recall may apply.

Gotcha! I was thinking external pieces and not the pieces going into the transmission.

It is the correct video in that it explains the reason we think the axle might be involved

 

[Macgyver]

Half shaft or hub bearing

Yesterday it was a video of the uniden radar detector. I believe it was corrected with the right video.

So it doesn't really sound like that but I still think you may be right. It sounds more like a piece of hard plastic slapping the firewall and not such a click like in the video. As a mater of fact I can probably count the number of clicks during the turn. I have a turn I make everyday and in that turn I think it clicks 4 times. It could also be described as slightly muffled. I'm going to open my window today and see if I can here it. I tried driving in circles and it doesn't do what the video shows. It only seems to happen on a more severe turn under acceleration. I even took it to a parking lot and tried hard turns under acceleration and couldn't make it happen. The car has 38k on it.

Glad it wasn't a naughty video!  Z

Could be a loose shield then.  The underbody shield has to be removed for servicing, perhaps one or more corners are loose enough to make a sound during the turn.  Or could be a brake dust shield but that would be metallic sounding.  Fender splash shield possibly.

I don't think it's the splash shield (that was my first thought when this happened). It sounded like an axle turning and the splash shield hitting it. But I'll check the underbody and the brake shield. I'll recheck the fender splash shield.
