Hey i have a 2013 Acura RdX with 129000KM on it i just got it I am in Cameroon and we don't really have these cars here or mechanics who are used to working on them. I wanted to know what might be the cause of this? And what is the

possible fix please

 

Looks like the camber is off. A four wheel alignment may be in order.

 

Agree with the 4-wheel alignment to check to see if your rears are in spec. I will say that in my experience, Honda / Acura Vans, SUV / AWD vehicles tend to "squat" (negative chamber) a little as they get older...though they were still in spec when I had alignments performed. The (2) Elements I previously owned were most noticeable.in this regard.

 

This usually happens with worn out rear springs.

 

Or worn upper A-Arm bushings...

 

Due to the design feature of the upper arm, its bushing is considered eternal and can only wear out due to tightening the bolt in the wrong position, but the ball joint can be dead, but then a knock should be heard while driving over uneven surfaces.
But springs are really weak parts in Honda cars.
