Hey guys, my zdx got a weird rattle at front axle on Monday when I came back from a roadtrip about 300 miles. The front axle is rattling when acceleration in 1st and 2nd gear and also breaking as well as turning steering wheel.

Yesterday I went to the dealer and they checked for me said there is a problem with the shaft assemble and they do not have parts now to replace it.
And they tell me to drive my zdx before the parts come instead of loan me a car. Does it any dangerous or risks while driving it cause more problems ( around 30 miles per day)?
