CV Angle ???

[f150_fx4]

So I just bought a 3 inch front leveling kit with the rear add a leaf. Well before I bought it I asked a few people and they said that would be sweet. Well now that after I bought it some people are saying that the cv shaft angle is going to be real bad. Should I be real worried. If one goes if I do put this on how much is it to replace. I just wana know for the long run.

[TheRoadVirus]

If I'm not mistaken, isn't there usually some sort of spacer to make the angle less severe?

[Skandocious]

I'm not very familiar with the new trucks... Is this a 2 piece driveshaft like mine?

Or is it a 1 piece with a cv joint like this?

His trucks front axle shafts (with some modification);

I believe there is bracketry that drops the differential to lessen the drive axle angles.

[slmann]

what kind of leveling kit is it?

will it actually change the angle of the cv shaft?

[f150_fx4]

its just a 3 inch spacer or whatever that sits on tops of the coil. I seen pics of 2.5 and it was a big difference. cause stock is pretty much straight and 2.5 was up there. Its hard to explain I guess if i can find some pics of one I will post them.

[f150_fx4]

did he replace the axle before or after the install? if it was after was it cause of the lift. sorry probably stupid ?

[blacksnapon]

He bought it lifted. So, after the lift.

[f150_fx4]

o im trying to decide if I should send it back to get the 2.5 I dont wana break nothing serious

[slmann]

so how did this turn out?

[f150_fx4]

well I installed the front today the add a leaf should be here tomorrow. It turned out really good I think. Took me about 2 hours on each side. Didnt think that was to bad. They said it should take 1.5 hours for a good mechanic. I dont work on trucks much. But here is the pics tell me what you think so far.

Wow looks great!!! Can't wait to see it after the add-a-leaf.

[slmann]

Looking good.

[f150_fx4]

Thanks. You think that cv angle is to big or no. I think I should be fine

[fords4life91]

The cv is pretty big but the way these trucks are designed the cv axles are NOT spinning when the the 4x4 is not engaged so the less you use ur 4x4 the longer they will last!!

AHHH skan ur not even talking about the right part of the truck and BTW thoes are not cv joints on the driveshafts they are slip joints lol they are not even close to cv joints... lol the new f150's have IFS... and insted of u-joints up front like our trucks they have CV joints which are inside the black boots...

[fords4life91]

I believe there is bracketry that drops the differential to lessen the drive axle angles.

YES there is!! BUT is costs alot of $$$$$$$$$$$$$$$$$$$$ LOL

[95bronk]

those are driveshafts, first one has a slip yoke, and a carrier bearing with spacers because of a lift kit (im assuming your truck skan)

CV shafts are axleshafts without U joints. IFS trucks have CV axleshafts, and most new cars.

Blaise, the angle of your cv shafts dont scare me. I think the will be fine.

The 2nd set of driveshafts that I pictured have a CV joints at one end, thats the part I was referring to, not the slip yoke.

And the only reason I posted a picture of mine is because I have seen the term "CV" used loosely to describe both ACTUAL cv joints and also just 2 piece shafts in general; though I'm sure the latter usage is quite wrong, lol

By definition-- CV joints are 'constant velocity joints' that are used to compensate for harsh driveline angles. On auto's you typically see two u-joints used together to form a single pivot point in the shaft, as seen on the black driveshafts I pictured.

[95bronk]

Reguardless, after pulling a sled 240 something feet dead weight 6K lbs, in 4 low, im sure you would have found your weak points right there. After the phone call it seams you did just fine. If they didnt break then i dont think they will break any time soon. Good luck man, truck looks sick!

NONE of thoes driveahsfts have CV joints lol!! CV joints HAVE TO be in a boot because they HAVE to be packed with grease!! here is a cv joint.....

http://en.wikipedia.org/wiki/Constant-velocity_jointI edited my previous post so be sure to read that.

Sorry I'm mixing my terminology. What I'm speaking of is a CV driveshaft, which utilizes double cardan joints. Google "cv driveshaft" and you'll see what I'm talking about.

Double cardin joint used on CV driveshafts:

CV stands for 'constant velocity'. It is just referring to the fact that the shaft spins at constant velocity, as opposed to a single piece driveshaft which does not.

[fords4life91]

ok skan i will give u that i guess.... i was just saying that those so called "cv driveshafts" doesn't have anything to do with what we were talking about!! LMAO
but no biggie i just really know my crap when it comes to front suspension designs...just ask mike LOL!!

[Skandocious]

ok skan i will give u that i guess.... i was just saying that those so called "cv driveshafts" doesn't have anything to do with what we were talking about!! LMAODude no doubt. I'm the first to admit that I don't know JACK about anything post-1996. IFS is completely foreign to me, so when I heard "CV" I was thinking about CV driveshafts, which I AM somewhat familiar with. Had no clue what CV joints were though :rofl:

[95bronk]

Anal(ly) obsessive of the way it works is what i think of it lol.... Im rockin' straight axles and U joints for the rest of my life

[Skandocious]

[95bronk]

Ride quality is for sissys. My next truck aint gonna have any suspension, axles will be welded to supports that are welded to the frame, not gonna be street legal tho lol

[TheRoadVirus]

For the sake of the argument, you both have IFS... lol.

[Skandocious]

For the sake of the argument, you both have IFS... lol.Nahh... Not by the true meaning of the phrase... Yeah it's kind of independent but not like the newer trucks.

[95bronk]

Independent Front Suspension ='s IFS

lol durrrrrr. Our trucks are independent front suspensions, TTB is fords stupid name of the axle design.

[Skandocious]

I know what IFS means... But the TTB is not the same as the new IFS that have the CV joints like we were talking about earlier. THOSE are the true definition of IFS.

smilieIagree
YEP I agree with you 100% skan!! Its still "IFS" but not ANYTHING like these new trucks. In my opinion TTB is kinda a BULL $H!T version of a IFS design.... lol

[Skandocious]

[95bronk]

Piece of crap? Not at all...

Edit: how can someone say its a piece of crap axle when they never even use it??

[Skandocious]

Because these front ends have to be aligned more often than I fill up with gas!!

It's just not a very strong setup. And no I'm not speaking from experience. This is what I've been told by people who DO use their vehicles offroad.

[95bronk]

Mines been aligned once when i got my new tires, No sagging at all, even after jumping at the dunes and hitting mud holes.

[Skandocious]

[95bronk]

Reguardless your going to have to build a half ton axle.. Id rather keep the articulation of my TTB and build that.

[TheRoadVirus]

Go check out FullSizeBronco.com, specifically the BroncoSpeed forum (Chris). Plenty of guys putting some serious abuse on TTB's.

[95bronk]

Thankyou ryan. TTB's Junk? You doooont saaaayyyy......

[fords4life91]

TTB is defiantly pretty tough!! **BUT** it defiantly has its weak points!!.....it handles really squirly when u lift it, and the beams are prone to crack!!

[95bronk]

Every axle has its weak points. Beams cracking? thats a first

[fords4life91]

Reguardless your going to have to build a half ton axle.. Id rather keep the articulation of my TTB and build that.

From what I've read "offroaders" always say TTB has HORRIBLE articulation so......

[Skandocious]

From what I've read "offroaders" always say TTB has HORRIBLE articulation so......That's what I've heard too....

[surewhynot]

My TTB experience. For what it's worth.

They have a better ride when stock, compared to a straight axle.

When lifted, they ride ok, but have alignment issues.

They're articulation is better than a straight axle but not near as good as other IFS designs.

I have seen beams cracked and the pivot holes wobbled out.

It's hard to safely lift them more than 6 inches.

[f150_fx4]

wow see what I started now. Its like world war 3 of ford trucks lol
