This is a picture of Sal FX4's angle. What spacer did he use? 2.5''? Also does anyone know if he had to trim or if he has rubbing? I know he fit 37's. Let me know.

Thanks

 

Yes he used a Daystar 2-1/2" spacer.

 

is it just me or do those angles look really steep?

 

I may be full of crap, but I think with u-joints the angle (as long as they aren't bottomed out and contacting the saddles) isn't important, it's the fact that the flanges the driveshaft is connecting to at each end are parallel to each other. I'm not sure if the same applies to CV's or not

 

Those angle look pretty steep to me.

 

CVs don't have to be parallel like ujoints. Those look like they are pushing the limit, and when he turns full-lock, the overall angle is going to be extreme.

 

does not look to good...

 

I agree Wandell, that looks pretty steep. When selecting my suspenion lift (SuperLift 4.5") I was concerned about extreme CV/Axle angles. I have added a view of my angle with 35" tires (Not the 37's as shown in the above example) I know these are different lift systems but I'm very happy with my angle(Almost factory) also my system states it can handle 37" tires but not to exceed 12.5" width. BoB

 

ouch angles look every steep but that 4.5 in supension lifts one looke great

 

So how steep is too steep? what is the operating range of F150 CV joints and steering joints? How much additional down travel does the truck we're talking about have left available? What percentage of the time is the truck used in 4X4? If, like 90% of us it's rarely and only at low speed then will it hurt anything since the IWE's are disengaged during 2 wheel drive operation?

My educated answer would be: I don't know.....

 

CV/Axles do pivot thru the range of the suspension system. And as stated most of us utilize 4wheel drive a small percentage of time compared to overall vehicle operation. The Constant Velocity (CV) and/or axle last longer when operated at nominal angles... True the axle does not turn/engage unless 4x4 is selected but having the CV joint at steep/extreme angles reduces the time between failures. As for changing the operation of the components I really do not know either BoB

 

I am new here and now I am concerned. I just put on 2" Auto Spring leveling kit on my 06 4X4, and the angles on my cv joints look like the ones in that pic. Has anyone else had this problem with the leveling kits, and is that angle too steep? Will this cause me some expensive problems down the line? Is this normal with level kits? or is mine not installed correctly? Any info would be appreciated.

 

I had a spacer/leveling kit on my last 2004 F-150 and at 20,000 miles my upper ball joints were shot but that was with offroading. The UCAs are $70 a piece so its not too bad, if you do have to replace them.

 

Thanks Thumper, that does make me feel a little better about this, u have any probs with cv joints?

 

No CV problems but I only had 20,XXX miles on it before getting rid of it.
