Hey. Anyone tell me what offset, if any. would be needed for a set of mags on a HZ Kingswood sedan? A pair of 8in x 15in alloy rims have come up for sale and the guy recons they have a 4.5 in backspace which appears to work out to zero offset. If these work out will then find a set of 7 x 15s...

Hey all. I rebuilt my M86 one tonner diff about six months back. Replaced every bearing (timken), new true trac centre and a new set of Dana 3.73 gears. Also took it down to a reputable diff shop to have everything checked and set up. Problem is its had a decel whine from the first drive...

Hi all. Thought I would post what we found regards a pinging supercharged V6 in the hope that it may help others with similar issues. My brother has a nice VX supercharged sedan that has been having pinging and rough idling issues for a long time now. Sometimes it would run ok but mostly would...

Hi. I have a genuine GMH 92149032 electric radio antenna out of a VX sedan. (sticker still on it) Broken mast so I ordered a Aeopro AP250 repair kit to fix it. Problem is, that mast will not fit as the plastic bush and metal sleeve are too big. I measured my sleeve at about 9.75mm but the AP250...

Wondering if anyone may have any M86 one tonner diff setup information, carrier and crown wheel torque specs, bearing preloads, gear backlash etc? Cant find anything out there. Have info on the M80 sedan diff but doubt it would be the same. No manuals I know of cover the M86. Holden dealers...

Have a VY series 2 one tonner V8 manual. Only had her a few months and love it! I recently had a rear wheel off the deck and noticed that it turned easily by hand. Other wheel was on the ground. The metal tag on the filler plug says it takes LSD oil. I know I will need to pull the diff cover...

Wondering if someone can confirm that the PVC piping is connected correctly on my car, which is a 6/2004 VY LS1. I have read posts on here that show a different plumbing setup to what I have so am unsure if what I have is correct or not. This is all I seem to have. No other pipes connecting...

Hi. Have just got a vy one tonner LS1 manual. It has a cat back exhaust but still running the stock headers. I see a few shorty style headers (pictured)come up for sale cheap and am wondering if they would be an improvement compared to stock headers? Yes, have read the threads on these and it...

Wondering if someone could tell me if I am correct in thinking that all Commodore VY VZ one tonners came with Borg Warner M78 diffs for the V6 and M86 diffs for the V8? I had someone tell me that both came with the M78 diff. If true, was the M86 an option? Thanks

I am swapping a VZ sedan engine and transmission into a VZ one tonner. Have just noticed that the sedan trans is a 5hdd but the one tonner is a 6hdd. Although all the trans connections appear to be the same, I was wondering if I may have a problem with the speedo drive reading incorrect or...

So I have a 2005 VZ one tonner with a stuffed engine and have just found a donor sedan (late 2004) with the right engine (10HBA) to go into it. The sedan engine has 210k mileage on it, starts and runs sweet as, no timing chain rattles from cold or anything. Service book shows it has had all its...

Hey Guys. Wondering if anyone has had similar problems. My brothers Commodore V6 (factory supercharged) has been playing up. Starts easy, but idles a bit rough. Engine can cut out at idle now and then but that does not happen very often. Drives ok but pings like crazy when accelerating up to...

In the process of replacing the clutch on a 2002 Commodore VU V6 ute. Looking at the Exedy SMF kit but have heard they can be noisy or I should say that the well body tends to amplify noise more than in sedans or wagons. Is this true? Would really like to hear from all the ute owners out...

Brothers VX V6 Supercharged Commodore had been running rough for a few weeks.. Really rough idle and stalling when started from cold. When warm it would do much the same but not as bad. Was also throwing a left hand O2 sensor lean code so we replace the O2 sensor. Car ran exactly the same but...

Hi. My brother borrowed his 'so called' mate his old VU Ute and he has now written off the underside after losing control and going bush. K Frame, engine sump (V6) and diff are all smashed. I was looking at purchasing a VX Sedan and swapping out all I need but after reading a few threads it...

Ok. Holden VU V6 ute. Car will crank, start then stop intermitantly. Sometimes will start and run ok but mostly it will start and stall a few times before it will start and idle. Every time it does start the starter motor sounds as if it is still engaged for a few seconds. Starter motor has been...
