Hi guys, I am new to this and this is my first post so please bare with me if I get it a little wrong but I need some guidance, I have a 57 plate Ford Ranger Wildtrak 3.0 Ltr Turbo Diesel and I have a problem with the 4 wheeled drive system in low range on a hill decent it jumps out of gear even if the land isn't rough so I had it in the garage yesterday where I bought it from and they are going to drop the gearbox out and fit new parts next week as it is still under warranty for 4 another months, The other couple of issues are when I break hard or break on a bumpy road surface the front off side (R) side break grinds and doesn't seem to work properly it sound as if the calliper or disc is broke, I have had this same problem for 8 months and the garage keep saying they can't find a fault with it and it should work that way and it is the ABS working but my argument is that if it should work like that how come it didn't do it from day one when I purchased the truck brand new it started doing it 8 months ago and I have been backwards and forwards to the garage with it, The last issue I have with my truck but seems to be a major one and I need guidance so I can get it sorted whilst my truck is still under warranty is when I have it in 4 wheeled low range not touching the accelerator at all in 1st or 2nd gear just using the engine to pull away it grips ok in a straight line but as soon as I put full lock on either way it spins the back wheel intermittent on the lock side and loses traction, Also I got home from the garage yesterday after telling them the problems I am having and I decided to try the high range I put it in 1st gear to pull across my road to get the angle to reverse onto my drive and it drove for around 10 feet then wouldn't budge it was as though I had put the hand break on full, I then put it in reverse as a car was coming and could have ran into the side of me and as I tried to reverse there was a loud clonking noise and it did start to reverse but it was still as though I had the hand break on full or as if I had let the tyres down flat the drag was immense, I then tried the exact same procedure in 1st then reverse high range and low range the exact thing it just wouldn't pull right, I would very much appreciate your help with the problems I am having so I have a better understanding on what I need to explain to the garage to get it fixed under warranty, They can also see that I don't go proper off roading with my truck it is just used to drive around various farms I go shooting on so my truck Hasn't been neglected or miss treat, Sorry it is a long drawn out post but I just wanted to get all the problems down and try to get some help from anyone who has either had the problems I am having or know what it may be,

Thanks

Mike
