Save your Tires and your CV Joints! Installation of a Diff drop kit 00 to 06 Tundra, Sequoia

[@DarkElite100]

I need to get a diff drop done. After installing a 3"/1" levelling kit on my Tundra, I have slightly positive camber (~0.5*+) on the front tires, which is pulling the same kind of "camber" tread that you have on your own tires here. It only took about 5K miles before the tread became noticeable on the outer edge of the tires.

[@gdupler1966]

The diff drop helps and prolongs the tires, but does not solve the problem. I went to a 4x4 custom shop to have the front aligned with more negative camber and that is very helpful.

[@tristonsullivan1896]

Correct me if I’m wrong but the diff has nothing to due with camber on the wheels. The only thing that would effect it would be the upper and lower control arms. It is recommended to upgrade upper control arms to assist the amount of adjustment on the lower control arm. And the angle / amount of movement on the ball joint

[@gdupler1966]

Dropping the diff allows you to regain some of the factory geometry and camber adjustment lost due to the lift. You are certainly correct that adjustments to camber are made through the control arms. If one lifts more than 2.5 inches on the first gen Tundra, and I would say various other trucks, then aftermarket control arms are necessary. I am running some new upper arms now and will show them in an upcoming video.

[@joeray5394]

Im still trying to wrap my head around how the cv angle which constantly fluctuates based on road conditions could effect the alignment. The hub is in a fixed position based off the alignment settings. . I think you might be confusing castor and camber? Hmmmm

[@gdupler1966]

@@joeray5394 Lifting causes your truck to have more positive camber(tires have less contact with the road),not enough caster(steering doesn't self center), and the toe will be off. The diff drop doesn't directly affect the alignment but it does help with the cv angles to make them closer to stock. An alignment is still needed and the way to provide more negative camber (and the other adjustments).

[@joeray5394]

@@gdupler1966 So we are on the same page, the abnormal tire wear in the video has nothing to do with the CV angles.

[@joeray5394]

Yes i think the creator of the video was a little confused above what exactly a diff drop does.

[@Trd2020]

Damn that it? I thought it took way more to drop it

[@gdupler1966]

Yes, not a whole lot to the drop, and not expensive.

[@trinidadrm]

did this help the tire wear camber?

[@gdupler1966]

A custom alignment with additional negative camber has helped the most. But that was after helping the geometry with the diff drop and new UCA's.

[@ronaldrussell5481]

If you are going to "drop" your diff then you need to do more than tilt the front downward an inch which really only has about a 1/2" at most effect on the CV axles because the rear diff mount is fixed. Need to install a real diff drop kit like a Phat that includes replacement arms, mounts , etc. It's from Australia, where it seems they understand off road mods a little better than elsewhere.

[@gdupler1966]

I am sure there are more effective kits for more money. This is just something to help with geometry for low cost.

[@mountainhopper9573]

I think tires are wearing that way because upper control arms need to be replaced to get geometry back because of lift.

[@gdupler1966]

I thought UCA's would help as well, so replaced those (seen in suspension tips video), but the biggest help has been a custom alignment with more negative camber.

[@tylermalmsten3170]

Did you notice any popping after Installation?

[@gdupler1966]

Good question! I have not noticed any popping on my Tundra. However, I have heard/seen some issues at full turn, particularly with Tacomas. Diff drop is only helpful at 2 1/2 to 3 inch lift and above. May want to shy away from the diff drop if lift is less than that. I have also seen issues with worn sway bar links and seen where some folks have used a kit to relocate the sway bar links.

[@tylermalmsten3170]

G Dupler yea I’m lifting my tacoma 3 inches in the front and still debating on putting the diff drop on. Thanks for responding

[@bbreede1]

I just installed a Dobinson's 3" lift and diff drop kit. I have a loud pop when reversing on an incline when I turn right. I've triple checked everything I can to locate the source of the pop. I am wondering if it could be the diff drop kit? I didn't like the looks of the angle between the spacer and the bushing and frame. Since it's dropping the front at an angle, the front has a larger gap than the back if that makes sense? Wondering if that could be cause. Just curious if anyone else has had this issue.

[@tylermalmsten3170]

@@bbreede1 I have a 3 inch Leveling kit, and installed the diff drop over a year ago and haven’t had any problems or heard any noises. I did watch a KZbin video of a guy that had the same problem as you on his Tacoma after he installed the diff drop.

[@jamesclark6384]

Im sorry but where your diff sits has nothing to do woth tire wear at all. A proper alignment after the lift is the reason for the edge wear

[@sudburyhouse]

Why do you only have to drop the front of the diff and not the back?

[@gdupler1966]

Axles and driveshaft hold up the other end of the diff. Changing the height of the front is enough to change the geometry.

[@elevatingmindss]

Did you have a lift? Or didn't have a lift and just added diff drop and did it help that tire putter wear⁉️

[@gdupler1966]

Yes, I had a 2.5 inch lift and went up to a 3 inch so I felt the diff drop would help the geometry. So far, so good. I would not see the need for the drop without the lift.

[@elevatingmindss]

Thank you for your response ‼️

[@sandiegoemsprotocols]

I don’t think diff affects camber, only axle and driveline angle. Did you get it realigned after lifting?

[@gdupler1966]

You are right. The truck still had to be realigned to affect camber. The diff drop did improve the angle to allow for better camber, but didn't directly affect the camber.

[@fogduker3131]

Dropping diff will not change alignment angles our spec

[@fkn16v]

100% CV or diff angle on an ifs has no bearing on tyre wear. My factory 120 series prado wears the tyres the same as the video, its just the nature of the vehicle.

[@RickySlatton]

Do they sell a kit like this for a 2015 ram 1500 4x4?

[@gdupler1966]

I have not seen anything this simple or cheap for the Ram 1500. There is a company called Zone Offroad that makes a diff drop/relocation kit, but it is around $150 and designed to work with a more complete lift kit.

[@Willfittsah]

I’ve gotten my tires aligned four times since purchasing my already-lifted tundra. It has a 3” bracket lift in the front. The front tires start creeping into negative camber, especially the passenger. Steering wheel pulls over time and tires have noticeable wear. Has you diff drop made a difference and do you think it’ll help my situation also?

[@gdupler1966]

The diff drop helps the geometry and prolongs the tires, but does not solve the problem. I went to a 4x4 custom shop to have the front aligned with more negative camber and that is very helpful.

Hi. Diffdrop kit do not make any reduce on tire wear or change camber. Diffdrop is to save your cv joints. If you want to reduce tire wear and change camber buy aftermarket adjustable upper suspension arms👍🏻

[@gdupler1966]

Yes, we talk about that in the description and other discussions. The alignment must be changed and the diff drop helps the geometry with an aftermarket UCA helping even more.
