Vibration Through Accelerator & Steering

Hi Guys,

When driving my 03 grande I've noticed there is a slight but noticeable vibration on acceleration, It's quite noticeable through the accelerator but also through the steering wheel (Not as bad though). In general can't really feel it through the floor of the car. I haven't been able to find alot of information on this. Low speeds its not as bad and the moment you let go of the accelerator the vibration disappears. Sometimes when its had a bit of a boot it seems to be less noticable and also depending on the temp.

I've recently had it lifted but the vibration occured prior to the lift. Since the lift thoguh I've noticed on slight acceleration when turning there is vibration through steering (only slight again) but think that may be to to with CV's althought both appear in good condition.

I had the gearbox oil changed about 15,000km ago and from what I recall it wasn't long after that I noticed the vibration. From the research i've done the only suggestion I could find is either Engine Mounts, CV's, Tyres balanced or Gearbox oil change..

Car has done 235,000km and its 10 years old so don't have high expectation, but Great car and when I got it couldn't get over how incredibly well it drove for a 4x4. Maybe I've been spoilt to drive in such comfort im a bit fussy but really its annoying at times and becomes worse after long distance drives.

Just wanted to see if anyone has had this experience.. I'm doubting the Tyre balance as I would have thought when I backed of the accelerator the vibration would be consistent.

Cheers,
Jesse

Does yours happen at 1600 to 1800rpm?

Yeah definately is most noticable around that rpm range!, If I give it a boot like overtaking then there is not really any vibration but cruising and then accelerating in that particularly in gear 3, 4 and overdrive is quite noticable.

It's just more annoying then anything! Use cruise control alot so I don't have to keep my foot on the accelerator

Does yours do it at 2500rpm in 3rd gear as well?

When you get a chance get under and rock all the drive shafts, looking for a bad uni joint.
Reason being had very similar symptoms in my 2003 and found it was uni join at transfer case going to front diff.

It did vibrate at 2500rpm in 3rd gear - seems to be lower revs in higher gears

Also depending on the pace you take of from stopped poisiton

My 09 diesel auto has the same issue at 1300 to 1600 ish rpm. Only happens when under power and worst in top gear. The vibration also comes through the foot rest at different rpm too. Not having driven another 120 I put it down to an undesirable trait of the diesel.
