carrier bearing drop

trying to alleviate the drive vibrations on my truck, heard some folks here talk about a 1/4" or 1/2" of washers between the carrier bearing. Slid under the truck this sfternoon to try this one out.

Slid under the truck and found that there already was about 1/2" of washers already in there . Maybe this installed when I had the drive shaft balanced but not sure.

any sense in adding more washers to it?

 

I go thru CB every 80K miles or so. Ready for my third next month. NAPA $89.

 

When unbolting the CB, do you just straight up unbolt it, do you need to do any pre-work before starting the actual processing of unbolting it?

 

none that ive heard of anyway,its just two bolts

 

There could be quite a bit of play in the washer, negating any benefits they are supposed to provide.

 

the bigger the washer is the better to, some 1/2'' washers are going to be more stable then 3/8'' washers.theyll be more stable side to side and back and forth.

 

you dont necessarily even need to use washers at all, if you have any scrap steel laying around you could make the carrier bearing drop out of that, it would look just like the one you can get from toytec but cheaper. heres the one that tacomaman06 made

 

they work pretty good too....all the sets i have made for people.......im guessing about 30 sets or so......i've heard no complaints.

 

^^^^^ did you use longer bolts, or are those the stock ones?

 

so just unbolt the two bolts...and insert the washers? The driveline is not under pressure or anything? Nothing else would fall off once unbolted so I don't need jackstands to support the driveline?

 

You need jack stands or just hold it up with your hand, it's not that heavy

 

do one at time so the ds doesnt fall on your head, put the truck in gear and have e brake on for a piece of mind.

 

you can reuse the stock ones, they are plenty long enough for that size drop but if you decide to put like an inch worth of washers youll need longer bolts. they are a different type of bolt to,they have like a tapered end so its easier to thread in.

 

can someone explain to my why you would even want to drop it at all? Is this for lifted trucks

 

thanks, that's what i was asuming.

yes, if you lift the rear, second or first generation, it changes the angel of the drive shaft in relation to the differential. the point is to lower it a little to get the engle closer to normal. reason for doing so is you can get some vibrations at lower speeds

 

I got my hands on some stainless steel slugs today from work

two sets of two, two are 3/4" and two are 1" thick. I will drill a hole through them and give thema try, just one thing where can I get some longer tapered bolts that hold the carrier bearing on? If I put these slugs on now with the original bolts the bolt won't even clear the nut welded on the other side.

 

I just removed a 6" DB lift from my 03 Pre Runner Xtra Cab. I didnt even think of the ctr support bearing drop till I saw this thread. Mine has 'at least' an inch of drop shims (to compensate for 6" lift?) Anyways, All Im running now is 3" CO frt and single AAL rear. Im gonna get rid of most, if not the whole stack. I'll report back with pics

 

you could try looking for some longer ones at an autoparts store near you, bring em in the one you have and try and match er up with one that is the same size but longer. make sure to use the same grade of bolt to. i could name a few places but i doubt there are any of them in the U.S.
