Default Knocking noise

I was wondering if anyone could help, I keep hearing a noise when I shift in either 1st or reverse once I engage the clutch and it hooks up. Any thoughts?

axle click! Do a search for axle click theres a service bulletin. The rear axles need to be retorqued and they usually replace the nuts

I have this same issue... I found this on another forum, looks like it can help us.

"
Difficulty level 1/10
Tools required: 36mm socket;
250 LB-FT torque wrench;
Hammer;
Center punch;
Wheel wrench

15minutes per side.

You can tell if you have this issue by pushing and pulling on the axle with the park brake released and the car in gear. (see picture) I had the issue on the Drivers side only. Passenger side was fine. As you pull on the axle you will hear the infamous click. Push it back in towards the diff and pull again, you will hear the click once more. This excessive play in the drive shaft is a clear indication you are working on the right issue.

Remove the wheel
Using a center punch and hammer, un-stake the spindle nut.

Be careful not to turn the engine when using a wrench to loosen and tighten the spindle nut. Turning your engine in reverse could cause serious damage. Ensure the park brake is on when turning the spindle nut. With this in mind, ensure that when you re-tighten the spindle nut that you have pulled the drive shaft from the diff before applying the park brake to tighten the nut.

Apply a thin film of grease on the spindle nut before putting it on the spindle. This is only to reduce friction while torquing the nut.
Once you have tightened the nut to 240 lb-ft, re-stake the spindle nut.
You should see about a 10 degree difference from where the nut was previously staked. (if reusing the original nut)

Put the wheel back on the car and test by driving forward and back with someone beside the car listening for the click.

My click is history.

I think your talking about sometimes there is a noise coming from the tranny/diff when you shift into first before moving?
