Front Suspension Upgrades, it needs to be better! (free downloads) 

Nice use of the car trailer as your vehicle lift. This avoids having to bend down to work on the suspension!

I'm happy to see your videos again, I like your improvement Have a nice moments with it

4130 will make it a bit stronger, but you could also redesign it to support that hub flange better and make the flange from a thicker material. At a glance, I can see a few places where you could create a more rigid structure, you could also add some internal bracing, or start with a laser-cut and CNC-bent main structure. I think the two biggest improvements would be to go with 4130 and to thicken that hub flange. Maybe thicken it and add some bracing to spread the clamping force from the bolts. The bolts could go through a boss that webs out to place a larger and more consistent force across the whole flange. It's hard to say without being able to carefully look it over and look at any interference potentials. Love this project. It's been fun to watch.

Hey Doug it's been awhile since I watched one of your videos because of going through cancer treatments and now I might have to do it again but anyway awesome 👍 job will be keeping up on all your videos thanks.

Ahhhhh the pursuit of lighter weight and enough strength..... R&D never stops. Drive, break, reengineer and repeat. These project are always a compromise. Just thinking of that woods ride we discussed when the breaks got hot..... I see formula one video's where the ceramic brakes glow in the dark. Crazy stuff.

G'day, Great video. It will be interesting to see how the testing goes with these upgrades. Maybe next time your out on the tracks attach some camera's to this area. Thanks for sharing the knowledge man. ✌️ Peace from Melbourne Australia.

Hi Mike, very nice upgrades and nice fab work as usual, Wratchet held up great on those jumps, will be even stronger now, catch you soon buddy😀😀

As always, thanks for all you do and for sharing your knowledge/design with the world.

I’m probably wrong but 4130 Cromo is a better material but to gain the strength it must be heat treated after welding to normalize. Regardless it will need additional steps to be stronger as I understand it. But glad you’re back. I thought maybe you took up fishing.

@Doug Bug, I think the hub mounting plate that you made should be the same thickness or thicker as the hub mounting flange unless it is made out of stronger material. You have to sacrifice weight though. If you look at those SXS spindles, they are made that way. The spindle that you made could work but it should be gusseted up and down also. The force being applied while jumping is from the bottom of the tire not on the front or the back of the tire, I think. JMO

This is great stuff! Since you're whittling down your unspring weight, do you think you might try some lighter weight upper control arms sometime? I see on a lot of race off-roaders that the lower control arm is usually pretty beefy, but often the upper is quite light weight looking. I gather the lower absorbs most of the real abuse.

02 thin wall hub flange lol, even the new one. I know that car don't weigh much, but on spindles always overkill it.

I'd be interested to know if the bottom of the spindle flange was bent further than the top? Unless the wheels you're running have a significant positive offset, which would make clearance issues worse there's going to be a leverage from the wheel through the hub trying to peel the hub from your spindle. If have thought aluminium would be way too soft for a rotor? I'd be surprised if steel doesn't need to be hardened or similar.

Have you thought of changing the mounting of the lower limit strap, from a single flange, into a double flange, to give that lower mount some more beef?

Hi, do you also have the problem that your welding helmet fogs up from time to time, if so. What can you do about it?

Good morning!

Could you bolt the spindle to the upright during welding to help keep it flat?

I’m curious when you had your main plate cut out why didn’t you just make the caliper bracket all part of it that way you wouldn’t have to weld it on yourself? Or is it just because that’s the measurements came Soso and it’s actually just pretty easy to hold it together kind of curious

How're those Locked coilovers holding up? I'm strongly considering them for a long travel suspension build on my utv.

thats part of the funn..finding the weak points.. 1/4" 4130 should help

0:07 yeah, probably gonna answer this but I have to ask before I forget what type of deal are you making your disc out of

Why didn't you make the caliper bracket and the hub one piece so you wouldn't have to weld on the caliper bracket
