Shuddering Rear end SV6

[impulsive]

Read end has started shuddering between 2.5 - 3.5 RPM in 2nd Gear only. I was thinking at first the rubber 'donuts' or 'coupling' that go between the diff and tailshaft or g/box and tail shaft.

Was also thinking CV Joint? Ill take it to a suspension joint for a check tomorrow. Anyone had anything similiar recently?

My vz had a bad shake/shudder at around 108-114km/h and was due to badly balanced tyres. Could be a range of things doing it tho so hard to narrow it down

LSD? Not the kind you take orally.

Although if ya got some........

[impulsive]

yeah LSD, hoping its not diff related

[heyitsEnricoPallazzo]

Maybe do a change and some friction modifier.

[impulsive]

diff oil change?

[heyitsEnricoPallazzo]

Yeah sorry.

[impulsive]

you think its diff related?

Im hoping its something simple, being that it comes at 2500 and leaves at 3500 rpm in 2nd only i dont think its a farked diff as it should be doing it more regulary.

Well got under the car this morning, worked my way along the driveline, burnt my arm on the exhaust, banged my head..

Just as i thought originally.. found a split in the gearbox to tailshaft rubber coupling, guess she's farked, $65 for a 2nd hand replacement. 2nd one i have replaced now..

Every time I go near mine it takes it's toll on my body. I wear gloves and a beanie now.

Never had a problem with the rubber couple myself.
