CTR problems

I don’t know if it’s just my CTR but I have funny problems and didn’t drive 6000 km in a jhar. i hear funny noises from the engine room so shhhhshh scratch but only if I’m in a walk up to low speed but not neutral… every time I go down ireg as steep as in my garage make the rear axle crack…knack noises at 3500 to 4000 is also a funny sound I thought imme the is normal it’s apparently not… in the last time the front axle sounds like loose… I have incredibly many scratchers but no bumps are scratchers because I live in the shitty forest and we don’t have a road ihc doesn’t know I’m driving very slow and was still faster than 180
