[Kolie]

Hey Guys,please help,my 2007 Hilux have a loud knock knock knock sound on the kalahari's sinkplaat pad,it sounds like something is hitting the cab from underneath at the passenger sides floor or somewhere there but i cannot find the defect.
At my Hilux's 140k service i reported it to the toyota guys and they repoted back that they repaired the cab mounting but the sound is still there,please someone help because an hilux does not need to sound like that

Check all the shock bushes. Have a look at the engine and gearbox mounts too.

If a nudgebar is fitted check the clearance between front cab bush and nudgebar bracket should be more than 10mm. Also check top brackets are not against the radiator bottom cradle

Nee man Kolie, is jy seker jy dink nie aan 'n AMAROK nie, hy knock knock op die sinkplaat soos sy voorste strut los breek.

Nee ernstig nou, myne het dit ook gedoen toe is dit die excaliber wat ek gebuig het wat effens los was, maar jyt joune mos afgehaal? Hoop nie dis enjin mounts of gearbox mounts nie!

Also check the door hinges. I had a similar knock knock and the driver door hinge was slightly loose. Other than that, check cab mountings, shock mountings, and the other stuff already mentioned...

Had a similar experience with my wait for it mazda tree to tree hatch back. And it started after I hit a pot hole. the top nut on one of my shocks had some how become loose, tightened it up problem solved.

Let us know what it was :?

Also had a similar problem, turns out to be the rockslider mounts hitting the cab at the passengers side.

If it's not your mother in-law, check your gearbox and fuel tank mounts

Make sure your jack & tools are not loose behind the seat!

Hi all

Ja na byna 2100 km is ek redelik oortuig die klap geluid was maar my aftermarket front bumper wat die voorste modderskerm geraak het,voordat ek hier weg is het ek 'n stukkie rubber tussen die bullbar en die modderskerm gefit en ons het nogal slegte paaie gery tussen Garies en Namakwa sands en met 'n mooi stil kajuit.

Baie dankie vir alle insette,ek glo ek het die knock gehit

Tot later
Cheers

I had the same problem with mine this past weekend and after a thorough inspection, I saw that the Diesel filter hang loose and knocked on the Inner Wheel arch when I either turned fast or went over a bump. I used cable ties to strap it down because the one side of the filter actually broke out... Check it out, it might be something small that will save you money and hours of frustration...
