another Intermittent Vibration

sorry I know their is another post about intermittent vibrations, but I didnt wanna thread jack so...

At very low (0-10mph) speeds their is a noticeable vibration that I can feel through the floor boards...

can you guys give me some pointers?

if more info is needed lemme know and I'll answer as best as I can!

 

have you tried lubing the u joints and slip joint?

 

No I'll have to look into this...

so basically I just need to lube the drive shaft?

 

yah get yourself a grease gun if you dont already have one and pump some lube(i recommend Lucas red and tacky #2) into the u joints at either end of the driveshaft and also the slip joint. check the center support bearing for your driveshaft while your under there,there shouldnt be to much play in it 1/8'' or so.

 

okay, I'll go out today and get a grease gun...do I need 2 types of grease?

also are these write-ups what your explaining to do?

I'm somewhat mechanically inclined, but I've never done this before so I'm being careful to make sure and do it properly!

 

oh an also I read that one of the joints shouldn't just be pumped full of grease...

is this true and which one is it so I dont over do it. (if their is one how much do I put in?)

thanks for helping a noob!

 

u only need the one type of grease,you can go with Lucas or an alternative is fine. when your lubing the u joints keep an eye on the cups when you see lube coming out of them thats when you stop. for the slipjoint youll know when to stop because the grease zerk wont let you pump any more in.

 

sorry, but where are the "cups" that I'm supposed to look at?

 

the outer most portions of the u joint are what im referring to,inside are many small needle bearings and also where the grease gets pushed into once entering through the grease zerk.

 

okay awesome,

I've been reading through the write-ups really carefully and I think I'm getting more knowledgable on the topic!

still a lil worried about messing something up :/

 

done...I still only put a few squirts in the furthest back (#6) zerk for fear of problems listed in the 4x4offroad write up...

Not 100% sure but I think it may have fixed or at least lessened the vibration...

Hopefully it doesnt come back!

 

right on man

 

How hard is the center support bearing to replace I wonder? I think I have a little more than 1/8" play in mine so I might need to check it out.

 

Im getting ready to do mine in the next few weeks..You need to take the back half of the shaft(at least) out of the truck..Not sure if theres like a slip fitting where the CB is or not.

 

Please let me know how it goes. Good luck.

 

...I wondered about mine too, seems a lil loose, but I'm gonna let it go for now and check it in a while see if it is noticeably looser or not, if so I'll have to fix it but it seems solid enough.

 

Check your rear brakes to see if they are adjusted too tight. I know, sounds wierd, but it happened to my Tundra. Backed off a little on the rear brakes and problem vanished.

 

Does anybody have a video of a carrier bearing replacement? I looked on U-Tube even and didnt find one. Mine seems a little loose too.

Thanks,

Hey guy's looks like you are all working on the same stuff as me on the 1st gens. Do you all have a zerk on the slip joint behind the carrier beaing? I wanted to grease mine but it has a rubber boot and no fitting...

Thanks for the help.

I also need to change my carrier beaing but havn't found an affordable replacement for the 2nd gen when I do I can let you know about the replacement.
