G'day Norm.
My Dec 03 Hilux SR5 petrol engine was fitted with an OME kit and I have a few comments.
1) Rear increased height is 50mm; front increase is 25 mm. This is within 'specs' as ARB put it. It is also acceptable to NRMA insurance as, they almost interrogated me regarding the heights. So, my car is in fact insurable. Make sure yours is "within specs" for insurance purposes. Don't know what the other 4by insurers have in the way of concerns.
2) Having had ARB 'alter' the vehicle (from Toyota's POV), the work now becomes subject to a LOSS of warranty on anything that is affected by the altered angle of the drive line. THIS IS MOST IMPORTANT. If you alter the drive line angles near the centre links, the engine or the vehicle may seem to vibrate - like
mine does.
Now, Toyota investigated the problem yesterday and stated that ARB's modifications are entirely responsible for the vibration. To find out whether it was the new
suspension, they simply removed the back drive shaft and drove the car using the front (in other words, the put it into 4WD and still drove the vehicle). They claim that the vibration disappeared.
I have had the ARB technician speak to the senior Toyota service manager to discuss the problem in 'technical terms'. ARB have agreed to look at it on Monday. I was really annoyed with the service of the vehicle by Toyota as, from a service they conducted in early June (one month before ARB had touched my truck) to remove a metalic 'clunking' type noise apparent when moving off from a standing start as the clutch is released, they returned the vehicle to me with the vibration clearly apparent to me...not to them so it seemed.
I then returned the vehicle to them a couple of weeks later (still no ARB work yet) and had a technician
test drive with me. He stated the vibration was the beginning of the end for the clutch...they replaced last week as a consequence.
Then, on the 4-7th July, ARB added their
suspension and, I still noticed the vibration. Not realising the significance of ARB inteferring with the truck before Toyota assessed the clutch issue, I continued to drive the car before having the clutch replaced last week.
The truck was returned to me last friday with shudder - not a vibration - that was MANIFESTLY worse than that which they would have noticed prior to replacing the clutch. The senior manager, the original drive
test technician and other assorted folks then tested the car yesterday and declared that the vibration the original
test drive technician noticed was NOT evident and, that it was a DIFFERENT vibration - attributable to ARB's work.
I am now stuck with the nuisance of the vibration - which in my untrained mechanical opinion, is the physical evidence of poor engine performance and therefore I would urge you to do the following IMMEDIATELY if you have already had your truck modified: have the OME fitters
check the 'spacer' to see if they have altered the angle to a point where there is ... even a very slight ... vibration - not noticeable on any of your model Hilux not modified with the
suspension.
It is very important you do this as, the tussle between owner, ARB and Toyota is not a position enviable to anyone.
ARB and Toyota were very polite but adamant that - either the problem has never been reported before or, it's not their problem. I have a very keen sense of how my truck should sound and feel and, they really struggled to notice. The only trouble is that fuel consumption declined and I lost a great deal of power - especially going up hills.

Please contact me via email on owenia@bigpond.net.au to discuss if you like...we could speak on the blower.

Thanks for the detailed response Dave. Haven't done the work yet.
I spoke to the workshop supervisor at the Toyota dealership where I bought the vehicle a couple of weeks ago. Told him what I planned. He said it will be OK and won't effect the warranty. But whether that will stand up later, who knows.
I'll drop you an e-mail to discuss in more detail.
Thanks for the info.

G'day again Norm.
Just been to arb in the 'gong and they fixed up my 'vibration'. Toyota stated that they had placed everything about 15 - 20 mm too high and that the work needed to be modified by the arb folks.
I went to them this morning and they said that it will be a natural consequence of changing the angle of the rear shaft, it will make a wobble which translates into a 'vibration' at certain revs.
In fact, he said that they are meant to wobble anyway. He dragged me under the truck and showed me how the centre uni joint area has a certain amount of flex created by rubber seals. When the shaft is raised some more...say for instance if I was to go back to them and fit 250kg
suspension rather than the 120kg I currently have, it will vibrate even more.
One thing I can tell you, the amount of fuel I use is now about 2 litres extra per 100 kms as indicated by my fuel stats. I can send you my spreadsheet if you like. They include EVERY SINGLE fuel receipt since the car was new except for the juice they put in to move it to and from
the wharf.
the 05 Lux i saw was getting 250kg OME. So, it would appear that the 'SPECS' have already been relayed to ARB by Toyota.
The ARB folks were extremely helpful. They noticed that the drive shaft peices were slightly out of alignment (about 15 degrees) and so, they pulled them apart and re-aligned them such that each of the uni joint spindles were in a row. This appears to have reduced the vibration somewhat.
Hope you haven't been spooked too much as, ARB know their work and Toyota were very willing (in the end) to assist in resolving the issue.
I am due to return to ARB and have the vehicle placed on the dyno.
Going up to
Cairns on Thurs to visit Tyrconnel Gold
mine farm stay and am really looking forward to finally leaving Syd.
regards
owenia
