I'm at the point of planning the next stage, which is the front axle. currently my axle is completely stock except for gearing. i decided that i do not want to dump any money into the mini truck axle (high steer, new birf's etc) unless i intend to keep it forever. the more i think about it, i really want a wider axle up there to eliminate the scrub radius that plagues these axles.
options are:
FJ60: this is a very appealing option since its the same width as the ifs rear and also is the cheapest of these options to buy. biggest drawback i can see is that aftermarket parts are tough to come by
FJ80: very good option, 8" HP third with e-locker from the factory. heavier shafts and birf's than minitruck, 63" wms only draw back is the price and the steering geometry.
Dana 60: Simple to put in, would have to have it narrowed some.
diamond: haven't got a quote from the company, but just talking to ppl who have them, i'd be looking at 1500-2k to roll it under the truck
TG rock assault: 700 for the housing, then buy birf's, high-steer, etc so prob in the same range as the diamond
I am on a budget so the last 2 options are out. I think the dana 60 would be fairly straightforward but i'd really like to stay toyota if possible. I've gone back and forth about the FJ60 vs FJ80 axle. what it seems to come down to is that if i want to keep leaves up front, the FJ60 is the better option since i'm not willing to spend 1k on the high steer kit for the 80 axle.
I've never done much research on 3-links but then i saw this:
Who reused FJ80 front suspension for SAS on mini/4Runner? - Pirate4x4.Com : 4x4 and Off-Road Forum
4landrunner build-up
This looks like a very affordable way to get a wider axle up front. basically just swap the whole front end of the 80 over, steering and everything. no aftermarket parts required. i realize this setup wont have 5' of flex, but i'm not building a buggy. as far as strenght goes, the HP 8" and beefier shafts and birfs should be plenty strong enouh for me. i've ran a stock minitruck axle with 35's for 1 1/2 years now w/o breaking anything, and i dont plan on ever going bigger than 37s. i realize things change when you add a locker to the mix, but i could always buy shafts later if i need to
here's a price comparison i threw together:
well thats where i'm at for now. any feedback would be appreciated.
