06 X-trail, 135000 miles, off-side front knocking noise.

Customer Question

06 X-trail, 135000 miles, off-side front knocking noise. complete new bottom arm, drop link, new suspension top mount. just passed its MOT yesterday. can't find any play anywhere. not nice to drive, constant knocking, seems to be worse after changing the top mount. any ideas would be appreciated.
JA: Where exactly do you think the noise is coming from? And how long has this been going on?
Customer: front suspension, sounds like top mount. it's been going on for months, but just changed all parts for MOT.
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: I've changed above parts myself, MOT yesterday passed. no play anywhere. still knocking. could it be the shock absorber (front strut)? no oil leak.
JA: Anything else you think the mechanic should know?
Customer: don't think so, cars been looked after, serviced regularly. purchased 6 months ago, with knocking noise (MOT passed yesterday, no play anywhere)

hello and welcome to JustAnswer!

Its definitely possible that the noise is coming from the strut, especially if you don't believe there are any loose components. There are many possible sources for a noise ranging from the strut, a tie rod end, ball joint, internal steering rack noise, sway bar links and sway bar bushings. Chassis Ears or a mechanic's stethoscope may be necessary to determine exactly where the noise is coming from.

I assume the noise happens over bumps?

Will it happen when turning the steering wheel while sitting still?
