Vibration with suspension lifts?

Do any of you guys with a extended cab have any vibration underneathe from putting a susp lift on? I guess i need someone with and older model like round 96' because of the 2 piece driveshaft?

If something does vibrate after the install it was installed wrong. I've put 5 lifts on Rangers and more on other trucks, there has never been a problem.

It depends on how you lift them. Mismatched pinion angle (it has to be complementary to the driveshafts angle to the transfer case) will cause drivetrain vibration. Usually you've got to get up over 2 degrees or so mismatch. Just lifting, assuming you don't change the angle, won't usually cause a problem.

If you use lifting shackles, that's another story. They DO change pinion angle and if it's enough you could have a problem.

Yes, and if you're not, it probably won't be bad. Again, pinion angle adjusting wedges can remedy that. Make sure you buy good ones. I bought some cast cheapies and they cracked withing 6 months. Of course, I beat the heck out of my rear wheeling a 2WD, so maybe that contributes.

They don't come with the kit. They are available in bunches of places that sell lifts and suspension stuff. Can't remember offhand. Search and ye' shall find!

"Pinion angle correction shims wedge" and so on are possible search terms to combine.

upgrade your rear drive shaft. its worth it. my b2 had the crappy C(onstant) V(elocity) boot style shaft. as soon as it was lifted it went bad. so i got the and no problems since.

what size suspension lift do you have? if its just the 3" BL you have than your driveshaft isnt the problem. BL wont affect pinion angles. even with my 3" suspension my driveshaft went bad and vibrated, and it has drop shackles.

i would suggest saving and replacing your rear driveshaft at the same time or shortly after. mine is from James Duff, but ive heard all good about these guys too, Tom Woods Drveshafts....http://www.4xshaft.com/

I have the superlift and it dosnt Vibrate at all, and with the superlift it dosnt change any of the pinion angles to where it would hurt anything, but they do recommend the new front drive shaft with a beefier CV joint. So really it just dependeds on what kind of lift u are doing and how u are goin to lift the rear, like with lift shackles or blocks.

Yeah but i dont think the newer rangers have the carrier barring with a two piece driveshaft to worry bout like i do? Atleast i thought. Im going with a 4" susp from superlift.

what do you mean by slide in?

thats the rear for a B2, your ranger is probably a little different (but principles are the same), i think the rears on B2s and rangers were the same through most of the 90s though. newer models im not 100% sure on. but....at the flanges their are 4 bolts that come unscrewed and just place the new shaft in and bolt back. now it does expand and contract at the center, that picture is not exactly what i have though. ill try and get a picture in day light on my truck.

The newer rangers dont have the carrier bearing, and if you get blocks with the lift, they should be angled to help compensate with the pinion angle difference. Mine were with my RC kit.

the rear blocks should be angled, mine are, which is the kit that dirty was referring to. I now own that kit. But my friend had his carrier beraing go out on him after he installed his lift. was a few months later. but he noticed the the carrier bearing needed a couple washers to lower the shaft enough to where it was ok. he went through 3 carriers before finding this out.
