4wd turning circle

[francophile1947]

Same size front/rear or different?

Yes I think they're supplied by Bassetts
Mine are same size all round

Until November I was running the standard 195/215 combination. Since then 215's all round for ease of fitting winter tyres & having a spare which fits all wheels! No difference in handling noticed, except that the front end is a little more vague in heavy snow/slush - though this may be due to the fact that the front tyres are down to 3mm (fitted Quatracs to the rear last winter & switched them to the front this year with new Quatracs on the rear, hence the fronts are worn more)

Mine judders like crazy on tight lock fwds & reverse, but its nothing to do with the transfer box viscous coupling - it has a limited slip differential in the rear axle that is set up (not by me) quite tight, I don't know if they are all like this or not. I believe most Bongo/Freda's don't have LSD's so yes, any judder is likely to be VC or propshaft but if it has an LSD then that is your most likely cause & it is normal for old fashioned LSD's such as the Bongo has. Makes them even better in snow or mud though so it is a trade off.

I use the same size tyres all round on my 4Wd bongo... It makes it possible to rotate the wheels every service to even out tyre wear.

Ah.........fair point

does the v c not need a level of heat,or rather does it not work as well in very cold temps, the viscus fan surely works in a similar way. i experience a level of judder in very cold temps,surely this is normal until it warms slightly,and becomes more fluid.

Hmmmm, could do - depends how stable the fluid is.
