Vibration

[BoyWhoCriedWolf]

Hi all,

Dont know if anyone else has experienced this but I get a pretty bad vibration off the line under full acceleration, does not go away when 2nd comes in. This does not happen all the time. I noticed it was workse when someone is sitting in the back. Does the Stagea had a rear LSD?

Next one. Sometime when turning the wheels with at a standstill or going forward very slowly whilst turning I get a vibration. Just wondering if these two problems are interlinked????

Thanks in advance.

Hi Ken, I get the vibration when reversing slowly at full lock. I have checked the CV's and they are good. I will be changing the radius rod bushes shortly for more caster. They appear to be a bit worn (soft) so they maybe the problem. I also get a bad (harsh) vibration at 160 kph, I will get the wheel balance checked, but it feels more tailshafty. I don't have any vibration in first or second.

I get same vibration forward or reverse, but not at full lock, and not every time. I had a similar vibration (acceleration) on my gtr race car, it was a centre bearing drama. The tail shaft should not affect my turning vibration should it? I was thinking lsd clutch plate prob, maybe transfer prob - I really dont know. Out of ideas. Let me know how you go though.

Cheers,

I too have a slight vibration when turning slowly. But i thought it was normal as when I push the snow button I got the vibration still but a little worse so I thought it must be the ALTESSA system thinking that one wheel was turning faster, whcih it does when turning. I think it is normal, but I will stand corrected.

I was getting vibration coming out of my Cam gear cover for a few days, but then it went away. i was worried my belt was about to snap

I'm getting my timing belt replaced tomorrow anyways, so hopefully that will solve that mystery.

Vibration under hard (not very hard) braking, no real suprise there but, anything that small trying to stop 1800kg of wagon is going to wanna argue. Rear brake pads worn out in 12 months, so I've machined rotors, put a set of R31 rear pads in at a 3rd of the price for the genuine ones and seems to be gone for now.

Yeah i get that bad vibration under braking too. figure i'll upgrade the brakes to a decent set of brembo's in the near future.

I'm not sure if it's just the ABS stuffing up or that the stock brakes are just crap

I changed the front shocks on the weekend and I noticed, when I have one front wheel off the ground, I can't rotate it. It is pretty tight as I can undo the wheel nuts (tyre service 120 ft lbs to undo them). If I leave it for a while, a few hours, I can then turn it. I assume this is the ATTESSA residual hydraulic pressure, this happen in the GTR's. Since I have the Stagea in Park, the tranmission is locked so the one wheel can't rotate independantly.

Keeping this in mind, the vibration when reversing is an indicator that the Stagea may have some form of LSD in the front. Anyone seen that mentioned in the specs?

I have a gtr cut coming in my next container. SK, do you know if the Staj/GTR tailshaft is the same length?? Another things that happens is if I give it a stab and then back off quickly the diff seems to lock and unlock rapidly -anyone else?

My understanding is that the front half of the tailshaft is the same, but the rear is longer:cheers:

Will have to give it a go then.

Thanks
