Hi all,
95 GT, AODE, 2.73 Diff, 90,000km (55k miles)
I've got a vibration in the car that I have pretty much narrowed down to the diff. Plus there is a deep whine back there too.
Symptom:
is a vibration that enters AND exits at 50, and then 70 kmph. Yes the car is a Japanese export version, so in mph it's about 30 and 45 mph.
What I have done so far:
Driveshaft, harmonic balancer deleted, new uni joints fitted and then dynamically balanced.
Replaced all the suspension bushes, saddles etc with Energy Suspension gear, (they were showing their age).
Replaced all the std springs and stuffed shocks with an Eibach sports-plus springs and pro-damper shocks.
Removed the dogbone, which has reduced the severity of the vibrations.
My conclusion:
The vibration is definitely coming from the rear, as sometimes it is fair, then after a corner it is worse, (seems to be synchronized a little with the position of the wheels relative to each other).
There is no vibration thru the steering wheel, which would point more to engine or trans mounts.
So looking at doing a diff rebuild, and am after recommendations for 28 spline axle brand, new ratio/brand and rebuild kit brand. Looking at 3.27 or 3.55 ratio, heart tends to 3.55.
I have an account with rockauto (onya site sponsor!!!) And have previously purchased thru Summit.
So what do you guys think I should go for?
Cheers.
