Thread: Alignment/ Tyre expert Perth.

Hi Gordon,
I like yourself thought this, however when I turned up with my wheel carrier on, long range tank and my fridge slide in the back the LR mechanic advised me to go and fill up with fuel, put the second spare wheel on, put the fridge in and put another 15 kilo in the back to allow for food and any other bits and pieces I may have in the back when I am travelling.
Did it make any difference I dunno, when I measured the wheel to arch clearance before loading everything up it was the same when I dropped it off on the ramp at Southerns after loading everything on.
As PerthDisco mentions there is a tech bulletin about this and like him I can't find it.
Like a good LR owner I just do as I am told and if the tyres wear incorrectly or the old girl behaves badly, I've done the right thing.

Found it. Bit old now and maybe not applicable to newer models but would mean they changed something;

Technical Service Bulletin
No.LA204-008V2
27 September 2006
Reissue
Please replace the previous edition of this bulletin.
This bulletin supersedes TSB LA204-008/2006 dated 31 July , which should either be destroyed or clearly marked to show it is no longer valid (e.g. with a line across the page).

Subject/Concern : Discovery 3/LR3 - Uneven Tire Wear

Models :
Discovery 3 / LR3 VIN- range : 5A000360-6A403382

Markets : All
Section : 204-00

Summary :

A customer may report a concern of uneven tire wear.

This bulletin has been re-issued to change the labor time to reflect the usage of the new tight tolerance geometry setting mode.
Cause : Certain vehicles may experience a degree of 'bush settle' after the initial geometry setting following production (this has now been compensated for using calculated geometry settings introduced from the VIN above). This 'bush settle' may change the geometry settings to outside of normal tolerance and may increase tire wear. This issue is not experienced on all vehicles and the toe sensitivity may be attributed to other factors.
Action : Should it become necessary to adjust vehicle geometry due to specific complaints of tire wear, or where the components detailed below have been changed, the geometry should be set to the target values detailed in this bulletin. These target values are within the geometry specifications detailed in the workshop manual but are purposely detailed to address the above concern.

Labour Time :
Operation Description Operation No. Time
Geometry alignment (includes tight tolerance mode - activate and deactivate) 57.65.04 1.80 hours

Repair/Claim Coding :
Causal Part : ALGN4W
ACES Condition Code : W6
Defect Code :

Service Information
CAUTION : When checking or adjusting front or rear steering geometry, the vehicle must either have a full fuel tank or have sufficient weight placed in the vehicle's load space to give the equivalent weight of a full fuel tank. The weight must be evenly distributed at the front and the right hand side of the load space. The fuel tank capacity is 86.3 liters (18.9 Imperial gallons) (22.7 US gallons). Depending on the amount of fuel in the tank, calculate the amount of weight which must be added:

1 liter of fuel weighs 0.8 kg (1.7 pounds).

1 Imperial gallon of fuel weighs 3.6 kg (8.0 pounds).

1 US gallon of fuel weighs 3.0 kg (6.7 pounds).

When setting suspension geometry specifically to correct tire wear concerns, or after front/rear, upper/lower control arm bushes component changes, the target setting for the rear (refer to the table below) should be to the maximum toe-in within specification (up to, but not greater than 22').
NOTE : Vehicles that have any of the front or rear, upper or lower control arm bushes changed should complete a ten mile road test before having the geometry set to allow the suspension to settle.

1 . NOTE : The air suspension tight tolerance mode should be activated when checking/setting geometry (refer to the procedure on GTR).

Adjust the front and rear wheel alignment, using the target setting values below. For additional information, refer to Global Technical Reference (GTR) Discovery 3/LR3 Workshop Manual Section 204-00, General Information, Specifications.

Target Values
Adjustment Target Value (degrees/minutes)
Front total toe 0° 02'
Left-hand rear toe 0° 11'
Right-hand rear toe 0° 11'
Rear total toe 0° 22'
