adventra vibration

[doug adventra]

i know this topic has been discussed before but can't find an answer

at about 100km/hr my wifes LX6 starts to shake and at 115km hard to hold on road
only has 142k on clock and it only started doing it this week
also grabbing and letting go a lot in trans under heavy acceleration more so up a large
hills not so bad on gravel has about half worn Michelin primacy LC tyres

maybe should have bought a captiva

When were the wheels last balanced?

When was the trans last serviced?

^what Sabbath said, check if you've lost any wheel weights
or if you been driving in mud/dust/dirt, check that there's no mud/dust/dirt build up in the inside of rim, if so clean.
drive shafts front or back could be a prob, is it happening to the front or back.
Maybe check transfer case oil, often neglected as it only holds 200 odd ml

will check transfer box tomorrow on hoist thanks

Not a coil breaking down under load?

car at tranny repair shop
vibration caused by cement stuck to rims as our roading repair guys just fill hole with mix then tip bag of cement powder on
top then water with a watering can . lots of repairs on 10km stretch to school bus

vibration caused by cement stuck to rims

That was the next thing I was going to suggest:whistling

Just got back from a Sydney-Melbourne-Sydney trip in my Avdnetra.
I was having similar symptoms at 100 kmph or over.
An alignment and a balance solved it.
