Front End Knock Over Bumps

[Marko R1]

hi guys,

funny noise appears but only when i go over a sudden bump (regardless of speed) i can be doing 10km/h or 60km/h & a little divit in the road will set it off - sounds like a thump "DOOMP" when it happens.

what can i check? ive got it jacked up so i can go over all of the nuts & bolts...maybe its a worn bush?

Could be the wooden board in that back of ya boot (The one sitting on top of ya spare tyre in the boot under the carpet), if not, do you have aftermarket suspension? Could be the shocks / springs 'rebounding' as the car bounces up and down.

I also have a knock sound but mine sounds like it is coming from the rear of the car. It happens over sharp bumps but is also very bad when turning Left over bumpy road but not when i turn right which is funny. It also keeps clunking over bumps not just one clunk. I also got a $14 28 point suspension safety check done and pedders could not find anything either. it is Like a rattle hopefully i can find it and if any one has any ideas let me know because it is driving me INSANE!!!!!

i just found the front end knock - after checking & confirming all nuts are tight i then jiggled the front wheels whilst on the jack, the noise is from the top arm where it mounts to the inside of the strut tower.

i can actually hear the noise from the top & see it move back/forth a couple of mm (when it should only move up/down)

hopefully this helps anyone else out there - now where should i get these bushings that sit in the top arm?

^^Sounds like you might need a new CV joint Boot / Cover...?

Did you check out ya tyre / caster rods? And I think there is one more rod, can't remember the name, LOL!

Check all around that area and see how you go...
