I have not read all 18 responses , so apologies if i am repeating. I did have this experience of drifting. My tyrepower person said the defenders in particular are camber sensitve to the road camber. he adjusted the front end to address this ( sorry dont know the tech terms ) and it has been fixed. basically he desensitised the camber adjustment and it has worked.
Ok, just been to the wheel alignment shop - alignment is perfect. The tyres are 2.3 all round, but tyre pressure does not affect the drift.Quote:

Err, shimming the radius arm fowrd one side will not change caster on an individual swivel housing as the axle housing is a rigid 'beam', this is achieved by slotting the actual swivel housing to axle housing holes, and rotating the housing slightly. If you needed an overall caster adjustment, then only offset bushes will help. Shims at the end of the radius rods will only effect the wheelbase each side.

JC, thanks for the info. not sure I understand all of it, but will check with my indie mechanic.Quote:

POSSIBLY, but a 4mm variation is pretty normal in Defenders, I have seen a D1 with 11mm difference:o. But don't worry - After the caster change via the method listed below, it may improve or get worse depending on which way it has to be rotated:DQuote:

Anyway, this may be the only way to cure the unequal caster, so more measurements RE the positioning of the axle flange onto the end of the axle tube needs to be investigated. May have been welded on rotated slightly:(

Agree 100% with this, hence my earlier question!Quote:

Ok, I spoke to the guys at 5th Avenue Motors who do the suspension work for LR Stellenbosch. They found a 20mm difference between the left and right wheelbase :shock:
The caster difference is only 1 degree
Landy will be going back to them to see if they can sort this out...
Hi All
If the left wheel has one degree less castor than the right and you drive on the left side of the road then assuming that your roads have some camber the car would pull to the left quite strongly.
I used to try and set up vehicles with about 15minutes more castor on the left with our fairly low camber roads here in the Territory. Hope this helps

Chaps,
Landy went back to LR CL yesterday who sent it to 5th Avenue Motors again. I just spoke to the technician who is working on my landy and this is what he said:
- Wheelbase difference of 10-15mm on the left compared to the right. They do not see many of these n Defenders but manage to fix 90% of them with a slight residual 'normal' pull due to road camber.
- They can fix it by re-positioning the wheel, but it will look 'out of position' when compared to the right. However according to him this will not affect wheel travel and is only cosmetic.
They are waiting for feedback from LRCL & LRSA before any repairs are done.
Hopefully this time it will be fixed.
