V40 serious rt. frt. wheel knock/vibration

Post by fptaylor22 »

Have a 2000 V40 with 2K on rebuilt engine all new parts, fluids, hoses, etc. Runs great except for a persistent hard knock / vibratuion coming from the right front (passenger side) wheel area. The knock occurs with each revolution of the right front wheel.

Within the past month, I have replaced both front shock/strut assembly (Bilstein OE) and something that looks like a tie rod. The car has four new tires, which I had rebalanced and rotated again last week, new callipers, and brakes.

it knocks - more so when I accelerate, and has started to chatter - almost as if the wheel might come off - or lock up - if that makes sense.

I hear no sound from the wheel area when idling or revved in neutral. All fluids have been checked. I’ve had 3 mechanics make different repairs without solving the problem. Appreciate any suggestions diagnostic tests, experiences, or sure bets.

check if that main gaint nut ( not sure how you call it) that holds wheel assembly to axel is tight. Or bearings.

Changing mechanics when working on a single problem may not be the best tactic.
Consider checking the 1/2 shaft (drive shaft) and its mounts and joints.
