Slow speed hard knocking noises

Greetings all,

is anyone familiar with these sounds?

When cold you hear a shark continues noise when steering (full lock). After a wile knocking noises are added.

After 40 minutes drive all the noises seem gone.

I created a video just before the noises where gone (worst part)


Any idea?

If it is a CV joint you will probably only hear it when turning not when going straight (when you shift and hear a clunk-that's a different noise and probably normal). You can climb under the front of the car (using a jack to lift) and have a look at both front wheels-see if the rubber boots covering the CV joints are torn - that would lead to a loss of packing grease which would eventually cause the knocking sound. If they are torn that is likely your issue.

The strange thing is that I drive a bit longer the problem is completely gone. So my first thing to do is I guess a front and rear diff oil change?
It has nothing to do with an oil change. Jack the front end of the car and wobble each wheel for any play, have an assistant look underneath when you rock the wheel up and down and left to right.

Also someone mentioned spacers, did someone play in the axles/bearings and put too much grease?

I had a similar situation happen on my car once when the lug nuts were not completely tightened down when using spacers. Check your lug nuts and the torque settings.

OP, if you are driving straight and there’s no noise but you turn and there is a noise this tells me one of two things: CV axles or wheelbearings. If you’re driving straight and it goes away after 45 minutes I don’t know what to tell you; that is odd. Jacking the car up and shaking the tire back-and-forth as TopCarbon said will tell you if there is wheel bearing or CV joint play. Other than that, you may need a mechanic to look at this.

It's a four wheel drive and when I drive straight the issue is gone except I hear one knock when I shift up but maybe that is normal.
Mine does it slightly too. Maybe not that much tho. Its called binding due to the 4 wheel drive apparently. I got all my fluids changed which def reduced the sound. I believe Jaguar trans fluid removes it completely but I opted for the oem spec in the end [emoji6] Try doing a search you should find it ok [emoji1303]
