solid axle vs. straight axle

What's the difference? Is it just the name?

yup. Also have heard "live" axle being used..

aka known as Full Floating or Semi Floating, depending on the bearings design at the outer end of the housing.

I have never seen solid axles used in an auto type application, Just early atv's

Or we could launch a solid vs IFS debate... :stirpot: :stirpot: :stirpot:

See that's what I thought but some friends called me at 4 a.m.!!!! Arguing over it and I told them that and they said I was dumb. But o well

i dunno, IFS trucks have a solid axle in the front too, at least toyotas. i prefer straight axle.

the term SAS is used so much that its funny hearing newbies say they want to put an SAS under their truck or 79-85 toyotas are SAS trucks.

Look for Walker Evans. He ran a custom D60 IFS, and eventually canned it for a straight D60. Looks beefy as hell though.

I will say that yes, Solid wins the articulation situations... but..

Some IFS can take the air time.

I got IFS... but it's Ford TTB. It's like IFS with solid axle hard parts and Ford I beam toughness. I piss apon fixed diff cv half shaft A arm IFS. That is about worthless for anything other than commuting. :kissmyass:

TTB doens't win the ramp contests, because it lacks the lever effect you got with a soild axle, but you can get articulation out of it, if you use softer springs.. most springs used in TTB lift kits are uber stiff... like 450 in pounds.. :wtf:

Allot of us RBV guys have found that Jeep XJ springs in a BroncoII gives a caddy like ride off road and lets the beams have some travel. Some are getting up 18" of travel out of their modded TTB with soft coils.

Other than the nicer ride, and the ability to get air without breakage apon landing.. I would rahter have a solid axle.. and will probably swap one in eventually.

what are these "solid" and "strait" axles you refer to? Will I be cool if I have them? can I get one at schucks?

I'm gonna put IFS and IRS on my cruiser, screw this solid axle crap. :clappy:

did you leave you IROKs as they were in the RobTTORA pics or did you flip them around...

have you wheeled them yet?

how do you like them?

i dont think i will buy a different tire to wheel, i love mine.

Allright you clown punchers. The proper term is "live axle"

A live axle is a type of beam axle suspension system that uses the driveshafts that transmit power to the wheels to connect the wheels laterally so that they move together as a unit.

A live axle consists of a central differential mated to tubes containing the driveshafts that connect the differential to the driven wheels. The differential is connected to the engine via a swinging propellor shaft and a universal joint. The complete assembly is suspended on coil springs or leaf springs.

Some live axles use trailing arms, semi-trailing arms, Panhard rod, and/or Watt's linkage to control the vertical and lateral movements of the axle. Others, particularly older vehicles, use Hotchkiss drive, in which the leaf springs provide axle location as well as suspension.

As with any beam axle, the advantages of the live axle are relative simplicity, lower manufacturing costs, and the fact that the axle and suspension systems take up little or no interior volume. Because the axle assembly is a fairly simple and rigid arrangement, it can easily be made stronger and more robust, which is an advantage for vehicles with substantial power or that are intended for rugged and/or off-road usage.

The principal disadvantage is the negative effect on ride quality and handling. The wheels cannot move independently in response to bumps. Also, the mass of the differential and driveshafts are part of the vehicle's unsprung weight, so the greater unsprung mass transmits larger forces to the body of the vehicle and its occupants.

Until the 1980s the live axle was the most common rear suspension system on rear-wheel drive cars in the United States. It remains common on trucks and other heavy vehicles, owing to its greater potential robustness, but many passenger cars have now adopted independent rear suspension instead.
