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.
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.
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
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.
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
@@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).
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.
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.
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.
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.
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.
@@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 RU-vid video of a guy that had the same problem as you on his Tacoma after he installed the diff drop.
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.
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.
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?
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👍🏻
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.
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.
