To diff drop or not to diff drop..... That is the question.

Yes I searched. A lot. I have found so much conflicting information. Just wanted to get some real world experience and opinions. I have attached a close up of all boots and both axles. My truck is a 2018 with a newly installed toytec lift kit. Truck has 3,000 miles. 2 inches in the front and 1.5 in the rear. Thanks for all the help guys.

 

Everything looks good, but what is the fluid/wetness all over the place?


Edit, are you getting a vibration after the lift??

 

I wouldn’t bother with it. I put in a 3” OME lift about 80,000 miles ago and it has been fine.

 

I have a SLIGHT vibration at times when braking hard but it's nothing significant. I think I'm just looking for something wrong haha. Just washed it.

 

Your angles are similar?

 

Only thing to look for is that needle bearing vibe. All else looks great.

 

Yeah I haven't had anything like that come up. (I don't think that would be anything to do with the braking) so far it rides as good as it did before the lift.

 

I never diff drop anymore, we throw them out in the leveling kit packages.

 

I have the ToyTec Boss lift with diff drop installed and TC upper control arms. about 3" of lift. I was getting the needle bearing vibrations so i replaced the needle bearing with the ECGS bushing. Still had some vibration. SO, i removed the diff drop and the vibration went away completely. I would skip the diff drop

 

Thanks for this. That was kinda my fear. I'm running with no issues now. Didn't wanna put something on to try and avoid issues and create issues.

 

I have a Icon Stage 5 approx 2" of lift installed and it was done by a respected shop. They laughed when I asked about the diff drop. Lift has been on a year with 0 vibration issues, hell truck rides way better than it did stock. I did put an ECGS bushing in though due to vibes from that, and its been smooth sailing. Don't think about it, but I highly recommend the ECGS bushing when you can afford it. It's only a matter of time. At least with my truck, I had problems within 4k miles after the lift. Truck had 35k on it though.

 

Yeah I figure sooner or later I'll have to tackle that. I kinda wish I had done it while I had it apart but I'll do it when it's needed. Thanks for the input man.

 

40K miles with out it. Not needed on 2nd and 3rd gen. Here are my boots at 3" lift.

 

Looks good man. Thank you for the real world experience. I appreciate you taking the time.

 

i did the dif drop last night on my truck. only 30miles on it. noticed nothing. question for the people with vibrations...after 100 miles or so did you recheck/ retorque all your bolts on the dif drop? I feel like thats a problem people dont do is retorque everything once all is settled a bit.

 

Wow i made a thread with the EXACT same title a couple weeks back.. scary

You dont need a drop kit,your angles are fine.Drop kits are a waste of money anyway.

 

Yes they are similar to these.

 

Your fine.
