I need to swap the gears in my '77 blazer's front diff from 3.73 to 4.56. How much should that end up costing (including labor, parts, etc)? Just a ball park range you know nothing exact.
it all depends on which carrier you have...if you have a 3.73 carrier then you either need to buy a thick gear or a carier...if you have 4.10 and up all you need is a regular gear...what gear is in the axel now..lochenjons said:I need to swap the gears in my '77 blazer's front diff from 3.73 to 4.56.

i was just sayong sometimes its cheaper to find some one with a carrier 4 cheap then buying a thick gear...i could be wrong but my 488 thick gear was about 100 bucks more than a regular from rieder racing...38377k5 said:There is no reason to get a new carrier as long a thick gears are made for that axle (they are for pretty much everything GM, definitely for a 10 bolt). I would guess $500.

lochenjons said:Great so I go there today and the guy says itll be about $900 now. $145 for the gears, $85 for the master kit, $20 for the seals, $50 for the carrier, $30 for freight and then there's labor which supposedly I'm getting a discount for for being in a local 4x4 club but it's still $560. So there goes my $1200 i had set aside for tires and gears. This leaves me with now about $100 for tires (had to get gas today so there went the rest of it). I gotta wash my truck too before they work on it which I've never done and it's covered in mud. So thats my rant for the day.
EDIT: its a d44 btw
