ok so we had a light fall of snow yesterday, but i decided to lock my hubs 'just in case' their auto hubs, so i just put it in 4hi drove forward about 20ft, stopped, back to 2 wheel drive and left the work car park. just as i got round a corner i heard a sort of whirring sound and as i came to a stop at a set of lights i heard a clunk from the drivers side wheel and when pulling off the whirring had stopped. further down the road the other wheel started whirring so i pulled over and as i came to a stop it clunk again.
Now thinking back i have heard it before on the drivers side when using it in the recent heavy snow.
Im i right in thinking the hubs are way over due a greasing, so have become sticky?. i did intend doing it once the weather had got better. Iv only had her 6 months so have no idea what the previous have / havent done.
