How cold? I've never heard mine whine at all but you may want to check your fluid level just to make sure.
I just use Valvoline 80W90. No need for synthetic. Bearing kits can be purchased from www.50resto.com I am sure. See I just take my car to my rear end shop and they just do it up when I have a problem.
I look at the manual , saying I should use 80w/140 or something like that. I bought RP from americanmuscle.com and 80w/90 is only weight they carry. when did ford change the fluid spec ?
RP sux, i swear to god - every test i've ever seen of their stuff finishes in the bottom 2-3
(oh, and i'm using it too )
Hold cold we talking??
When it was 10 degrees out the other morning...everything on my car whined for a few miles
I beleive that now that im using it, and I like regular oil then synstec oil now too. What good brand for tranny and rear diff ? for my 1998 mustang. thanks
