axle strength

[rayning lead]

My f150 has stock axles other than 4.10 it has 9" of lift and 33 12.5 and it looks kinda dumb anyways I  just got a great deal on some 38.5-12.5-15 gumbo mudders my truck will clear them but what will my axles have to say about them my truck doesn't go to mud bogs since its my only vehicle its a dd but I do take it down some 2 tracks every now and then I can't afford a d60 swap I thought about a straight 44 out of a late 70's but after some research there barely stronger than what I got but my rig isn't wheeled hard and I know what its capable of and what's its not it's also a 5 speed with a 302 around 325 hp will my truck handle these tires with my driving style

[4x4xdodgeman]

yes  all day long

[Hammerlane]

Yep, keep it in the driveway and only wheel at the mall and you'll be fine..   
why build a 9" lifted on 38's to drive back and forth to work   attracts too much attention from the authorities.
stock axles 1/2t, 3/4t, 1t,.
that's alot of extra gas money pissin out the tailpipe.
I've had Gateway gumbos before.. respectable tires in the mud, will wear quickly on hard surface driving.
if your just trail riding I'd drop it down to 4" lift and go with 35's or so, better performance from drivetrain (ujoints) and you
wont have to regear to maintain low end grunt.  smaller tires will provide less unsprung weight and maintain better MPG.

I bought my truck this way with the 9" lift I just put a new motor in I only drive 6 miles on dirt roads to work and it has 1/2 ton axles. The reason I asked this question is I've done alot of research and some people say no bigger than 35's some say 37's some say I'll be fine with 38's if I know how to drive figured I'd ask before I bolted them on or trade for something smaller

[rayning lead]

I just rebuilt the front end by the way with the bigger spicer u  joints if it makes any difference its a 6" suspension and 3" body

[betterbeaters]

I never had good luck with 1/2 tons hell I broke a d60 1 ton with 35s and a stock 305...  I wouldnt put bigger than a 35 of a full size with 1/2 tons.

[Blazin40s]

With the taller rubber you'll loose lot, hut if u just dirt road it then who cares.  I know that combo wouldn't last with me driving, but I have a heavy right foot.  If u take it easy u will prob be okay..... In two wheel drive.  Ifs and 38s won't last offroad.  May even have trouble on pavement if u put four wheel drive on on the winter.

[rayning lead]

Well I'm trying to find some 60's but they are so expensive I can do the swap no prob its just money wise can't afford it would there be any benefit if I went the cheaper rout with a solid 44 right now I have the ttb and my friend has a 79 high boy with a coil sprung d44 straight he said I could have for 50$ but what would be the point if there both Dana 44's is there anything you can do that's cheap to strengthen the ttb

[85cHeavyMetalBogger]

i think u would be all right, just keep tires on the ground..

[rayning lead]

Yea that's what my buddy said keep them on the ground he said he ran 44's on his 1/2 bronco but it killed it so he went back to 38's he said I would be fine but wasn't sure.thanks for the input I'll put them on and see what happens

[Blazin40s]

Solid axle is stronger, put that on for now, and when u can slap in a d60

[jbeery78]

i run 38 in hawgs on my 78 with a 44 front and an 8.8 rear, welded rear open front and i cant seem to break anything. And trust me i try haha

[Jjay78]

hey man i got a 78 1/2 ton with 8 inches of suspension lift 40s and a 44 front, no problems with it at all, and i beat the out of it

[Kyle]

I have a 44 front and a wimpy 10 bolt rear. Beat the crap outta the truck and even jump it. Burnouts and brakestands with 450ft lbs of torque comin outta the motor. Youll be fine

[Blazin40s]

I broke my 10 bolt with my 39.5s

gotcha..
if your drivin it soft/easy should be no problem.

[rayning lead]

Thanks you guys I'll see what happens with them on if stuff starts breaking I'll put my 33 back on til I get a 60.

Don't want to sound stupid here, but I had 10bolts on my k5 with 40" hawgs, and I'd put the hurt on that truck befor I started the resto. Axles held up like a tank, except when I had 35s, I couldn't keep the front left u joint to safe my life. But I never broke shafts.

not to start a fight but..
Hawgs are not really a good "Hook up" tire IMO (unless they're cut)
Swampers/Boggers (or something akin to them) would change that "aint' breakin" thing drastically.
other variables are mud and it's consistancy, HP, gearing etc...
