Holden VZ Check Powertrain issue pt 1

I have had 3 new diffs in a year and the latest one still clonks and rumbles. Holden are adament there is not a problem with the diff, but change them anyway??? I have heard that this is an issue with all the V8 range, anyone had similar problems?

I have no idea what model diff, I know that it is limited slip though. The Holden dealer service manager tells me that this is not an isolated case, apparently all the diffs on this model suffer.

Other problems are, the vehicles load carrying capacity, it is rated at kg, but at anything over kg the tyres rub on the inner wing shrouds under cornering and the axle is prone to coming out of alignment, leading to excessive tyre wear and crabbing.

Previous Topic Next Topic.Hi Everybody, Straight to the point.

I'm onto my third diff in my VZ Crewman and I'm starting to get clunking noises from the drive train somewhere after driving for awhile and after you have been around roundabouts and corners. It is a manual 6 speed and it's starting to get me concerned. Anybody have any ideas as to what maybe going on back there and how I may stop the clunking. Car is only just 12 months old. I still have to take it back to the dealler yet to see what they have to say. These live axles are an ongoing pain for Holden and all it's dealers.

Working at a dealer as I do, there is little more that can be done than dealing with the issue when it arises Think it's time to return to the dealer who put the last diff in and see what they have to say. Problem is it only happens when the diff has warmed up and it doesn't happen all of the time. I've heard of this from many Crewman and tonner V8's with dana diff owners since I have owned mine.

It seems no matter how many new diffs you throw at it, I am assuming that if the clunking noise is not related to the LSD component of the diff, then it has something to do with the angle of the pinion to crown wheel ie; design which can amplify any backlash.

Anyone please feel free to correct me if this does not ring true. Maybe a question to Diff Technics in the Sponsors section might shed some light on the situation. Cheers Chris. Went back to the dealer and had the mechanic go for a nice drive with me. Yep, no noise except for once and it was very soft. He thinks it is a pop and not a clunk. Said it is very hard to find the problem and does not think it is the diff but maybe the tray flexing. Said to keep an eye on it and if it gets worse or all the time bring it back.

So i guess I'll just keep going how it is and hope the back side doesn't fall out whilst I'm driving down the highway at a great rate of knots. Cheers Mal.In other words like a faint but distinct grinding noise that is slowly getting louder.

The local Holden service centre had three mechanics have a quick look hoist and stethoscope and a drive of it it prior to it's scheduled 30k service in a couple of days. All agree they can hear the noise and each said independently of each other "I think the Crewman has had an acknowledged diff problem".

Anyone know of such an acknowledged problem? Check your Private message Thanks indeed. See yours for reply ; As a general small update on this I rang another dealership and asked if there were any known problems with Crewman diffs and they said "Just bring it in and a mechanic will test drive it and it we consider it is noisy we will order another diff from GM and fit it for you". I now wonder if I have to argue the point about what is considered noisy!?!?!

I had a run in with my dealer this morning. Took my Crewman in for its k service and to get a small stone chip fixed when i took delivery had a small chip in bonnet, dealer agreed to respray bonnet when i come in for k service Anyway i went to pick up car today and bonett had benn buffed but chip was still there, the service manager thought i'd find this acceptable!

I now have to wait another couple of days, the free executive commodore loan car i had is now upgraded to a demo SS. Gonna lay some friggin rubber later! However it's apparently rather prevalent. In fact I had a circuitous argument with customer relations on that point.

They couldn't tell me what scale or method is used to determine whether it is considered noisy or not. Mine is getting VERY noisy and it seems it's the pinion bearing. My "S" has done 28,km. Furthermore it seems that GMH is having hassles with the diff supplier as the application and determination as to whether they will replace it or not swings on the dealership returning a faxed application sheet to the diff supplier - not GMH.

Fortunately I heard today that they will replace it. Trust me - it's noisy. I scored one of those built with the leather trim "smart pack" a few months ago in expectation of large orders.

Those orders for leather option didn't happen so they released them with "free" leather and free rego. Same colour as before - Redhot. The V8 has a different diff otherwise I wouldn't have been so keen. Just thought I should put the word out about the diffs. Good luck Fitzy44 BTW what did they slug you to changeover? Fitzy44, Are you sure that a V6 diff is different to a V8 diff.

I thought that they where both the same unit? Anyway congratulations on the upgrade, and as for the colour, Redhot looks great. As for the diff - beware as you have probably also upgraded to diff whine. Cheers Chris.The diff in my VZ Holden Crewman is making a clunking sound, even though it? Is it true that the diffs are a problem in the Crewman as a few people have told me?

Sorry to tell you but the diff problem is a common one in the Crewman, has been since it was new. Please note: Questions cannot be answered privately.

My Crewman "S" has just developed a noisy differential. Anecdotal evidence gained by querying its prevalence at several dealers gets the response "Yes - we've had a few. Just bring it in and if we think it's noisy enough we'll get another diff and put it in for you. In fact I had a circuitous argument with customer relations on that point.

They couldn't tell me what scale or method is used to confirm whether it is considered noisy or not.

Ewan Kennedy road tests and reviews the, and Holden Adventra and Crewman as a used buy. If it has come on and stayed on it means you should get it checked, it could be a number of things that caused it, and you need to have it checked by a mechanic to determine the exact cause.

If there isn't any obvious change in the way the car drives there's probably not much to be concerned about, but it the car isn't running the way it was, and the light is still on get it checked. I'm not sure of the date, but I understand the 7. That should tell you if your engine was affected. It's hard to suggest what might be wrong without seeing the car, so I suggest the best thing is to have an LPG specialist look at it. Give the people at Impco a call on 03 and ask them to check the car for you.

That's the problem when trying to locate the cause of leaks etc. They're not usually the obvious things you think of, like a poorly fitting or damaged seal etc. Ewan Kennedy reviews the,and Holden Adventura and Crewman as a used buy. I would approach Holden with a claim for part compensation, the only to do it is through your dealer in the first instance, and then direct to Holden of the dealer rejects you. If they did agree to your claim, and I doubt they would, they would most likely supply the parts to rebuild it, and leave you to pick up the tab for the labour.

Ignition coil failures have been an often reported failure on Commodores going back a number of models; it's not necessarily something new.

I couldn't say the others will fail any time soon, after all the two failed coils didkm before giving up.
