Using the alum. front diff seems not to be working for my driving or lack of talent. the anvil is the answer but i am $8000.00 less the truck, into it now i need a cheeper answer for the summer time I have been told that the newer vitara has a cast diff. that might fit Has anyone tried this yet. need the make and year to get one and give it a go. my 97 side kick is a rear wheel peel for a week or two and it just is not right. (i can still go more places than most jeeps lol i think this is funny... )front A.R.B might be another answer but alot of work to put on a week link.
