TTB frame?

[85_Ranger4x4]

Twin I beams are far superior for bouncing down rutted dirt roads and pothole laden highways.

For 4x4 mainly because they have servicable wheel bearings.

It isn't like SLA breaks a lot of control arms or anything.

Right. The big advantages to a TTB front end, for a DD, are that parts are cheaper, but usually take more work to install.

On road a TTB can be made to ride just as nicely as an IFS.

I had a 96 F150 4x4. Then a 97 Expedition 4x4.

The F150 rode like a cadillac compared to the expy. The expy also didnt flex as good off road, and constantly needed aligned after a decent thrash thru the rough stuff.

The F150 i had air borne once or twice, would hit washboards/potholes as hard as i pleased, whatever, and that TTB tracked straight and true thru it all.

The ONLY advatages the expedition had was turning radius and the fact that it had more responsive/tight handling. Which, really, to me isnt as nice as the heavy, vauge ford truck feel.

The only reason ford abandoned I beams was because yuppies couldnt go racing around on the freeway at 100mph without ending up on their lid. The Eseries (till it got killed for that eurotrash transit)as well as 2wd superduties still use them to this day.

After 13 years and 150k miles of testing the only complaints this yuppy has about his '02 F-150's front suspension is unit wheel bearings and upper ball joints made into the upper control arm. 0 alignments to date. Untold number of wedged cornstalks though.

No central list that I know of. Just ask what you need.

SLA = short/long arm suspension
IAC = idle air control
IAT = intake air temperature sensor
ECT = engine coolant temperature
SAS = solid axle swap
FUBAR = f***Ed up beyond all repair
Lol = laughing out loud or laughing online

This answers a lot of my questions but I thought lol was " lots of love"

Ok.
" Lots of love" it is.

IFS = Independent Front Suspension?

 

[rusty ol ranger]

Actually TTB/TIB is IFS if youre being technical.

However torsion bar/macpherson/dual wishbone whatever is usually what is reffered to as IFS and I beams are reffered to as I beams.

Well if you want to get really technical it is semi-independent. The two sides can flex independently, but the have more effect on the opposite side of the frame than a truly independent suspension would.

 

[Ranger850]

so is SLA an IFS Or TTB/TIB is SLA and IFS I'm so confused. I thought all fronts were IFS unless it was a solid axle.
and isn't SLA and TTB/TIB the same as uneven I beam suspension, like I had in my 2wd '83 ranger, where one arm was short and one was long?

 

[rusty ol ranger]

SLA is "short long arm" 98+ Rangers.

TIB/TTB is actually a swing arm system i believe.

Both are forms of "IFS" but different styles. A solid axle is a solid axle.

Your 83 ranger had twin i beam.

So yes, either you have IFS or solid, but the term IFS applies to any front suspension capable of moving each wheel up and down independently, regardless of the style of IFS used.

If you really wanna be confused there are also differnt types of solid axles, kingpin, ball joint, link arm, open/closed knuckle (4wd only)....

 

[adsm08]

SLA is IFS.

TTB/TIB is technically a form of IFS, but Ford classes it as 'semi-independent" like I said before. This is because the two sides can flex through most of their range without moving the other wheel up or down, but it does move the other side of the frame more than an SLA system would.

SLA is a truly independent suspension system.

TTB/TIB is not SLA.

In a short/long arm suspension there is a long control arm,usually on the bottom, and a much shorter one on the top. While the beams of a TTB system are not perfectly even in length, they are very close. They are also not control arms.

It is rather amusing just how independent a TTB really is though.

Oh TTB is awesomely independent, especially for how strong it is.

Just think about the fact that they used this setup in 3/4 ton trucks, and didn't have it breaking regularly.
