1st Gen 4x4 / Prerunner Carrier Bearing Drop Bracket

Here are 3 different brackets....the first gen is the only bracket that uses a long 5/16" bolt with either a nylock nut or a top lock nut, depending on my supply at the time. The bolt is long because it goes through a boxed cross member unlike the 2nd gen Taco & Tundra. The 1st gen (95.5-04) bracket works on 5 and 6 lug trucks.

The second gen Taco and Tundra use fatter 1/2" bolts up top, and the same goes for the nut, nylock or top lock, depending on my supply.

Also, depending on whether the bracket is a 1.5" drop, or a 2" drop, will determine the bottom bolts. The 1.5" brackets use metric bolts that replace the stock ones to bolt the carrier cage to the bracket and the bracket to the frame. The 2" brackets use shorter standard bolts below to attach the carrier cage to the bracket, and the OEM ones get reused to attach the bracket to the frame.

left to right...2nd gen Taco, Tundra, and 1st gen Taco. (all 1.5" drop)



2" style...you reuse your OEM bolts to attach the bracket to the frame. 2nd gen Taco pictured. (This was actually a 2-3/8" drop for DOM, Tacoridinhigh. He said it helped immensely)

 

well i understand what you are saying about the nut, and yes its one of the nuts with the plastic not an actual wing nut, i just didn't know the technical name. So i assume now that the setup will indeed be fine if the nut goes on more with a tool than can be done by hand. And if you look in the next post by Brian, i have the smaller 1.5" bracket as seen in the picture, so you also answered my question that the stock nut must be reused, since there are no nuts provided and we just provided me longer bolts since their is only 2 needed rather than 4 bolts on the larger bracket

I see now. Did not know there were two sizes available for the 1st gen. I guess I have the 2" drop as my bracket looks quite different than the pic Brian just posted. He also explains why you have two longer bolts with no nuts. So in your case you would not need to use the stock bolts. Just use those two longer bolts to bolt the bracket & carrier bearing mount onto the subframe all in one shot. That would make your install easier than mine. Now hurry up & go install that bad boy.

To add, I never had drivetrain vibes even with my lift but it did completely eliminate the thump from the yoke even if I haven't greased it in a while.

 

Hey that's a good point. I never thought about it curing that issue too. btw, the reason yours looks different is because you have a earlier version that was made slightly different on bottom and yes, yours does drop down in the 2" range. These brackets have undergone a couple changes as most products usually do as time goes by. Your one of the OG's for the 1st gen brackets.

 

Just got my 1.5" carrier bearing drop from Streetacos last Monday. I got it installed, but it made the vibrations worse!

But hold on! I took my truck to a small, specialty driveline shop to trouble-shoot the issue (I was feeling like I was in way over my head, so I thought I'd get a professional look at the issue). Turns out the carrier bearing was completely shot because the slip yoke had shed a weight and ground up the u-joint in the back at some point. The extra stress on the carrier bearing had caused it to fail.

Long story short, got the driveline rebuilt (where it had gone bad, with a new slip yoke, u-joint and carrier bearing) and left Streetaco's drop kit in there, as the shop tech/owner (it's a 1-man operation) said it would do a lot of good in keeping the stresses to a minimum. And he really praised the build quality and design of the kit -- said it was the best looking one he's seen in 20 years in the business!

Props to Brian/Streetacos for a great product!

 

Wow! What a story....I got scared, then concerned, then scared again, then very happy at the end! Your post is like a carnival ride! (without the throwing up) Thanks a bunch for the 411, and that means a lot coming from a professional driveline guy that's been doing what he does for as long as he has. Thanks again for posting up David, much appreciated!

 

Just ordered mine, can't wait to report, as my vibes are horrible!!!!

 

Just order one of these bad boys! Hopefully it solves my vibrations!

 

It works awesome...paired with a 200$ Toyota Carrier Bearing, The vibration went away. Not to mention I didnt read the note to allow time for fabrication yet he still got it to me when I needed it....Now I need a Front Bumper.. .

 

Not totally sure which one I should go with… The back is right at about 4 to 5 inches I think. I don't want to buy the wrong one since there aren't any refunds!


And yes, I have a front lift on the way haha
