sorry if there is already posts about this but I've done a little research and haven't found what the problem could be...
First off, I have a 1993 bronco AUTO, 351 windsor bored 30 over, it has a 9 inch suspension lift, ford 9 inch rear axle with 4.56 gears and locked with a spool, and a dana 44 front axle that is gutted at the moment so no 4x4...I had 36 inch super swampers on it but needed money so i sold those and only could come up on some 33's so thats whats on it now...
i never noticed the noise when i had swampers on it but now driving down the road this thing screams, it has a real loud whining/ grinding noise while accelerating, it starts at about 1.5 to 2k rpm's, when i am all the way on the gas or mostly on it it whines LOUD and when i let off a little but still slightly on the gas the grinding noise starts, if i let off completely no there is no noise at all...
the other problem is a CLUNK noise it doesn't do it to often only a few times since i had this rig but usually when I'm slowing down and it shifts back into a lower gear...
PLEASE I NEED HELP ASAP, i need to get this thing fixed as it is my daily driver and I'm starting a new job next week, and as of right not its up for sale for $3300 obo so it'd help to sell it if i got these problems fixed other then that it runs and drives like a champ, couldn't go wrong with a FORD
THANKS FOR YOUR TIME AND HELP
