I think Crackers point was that you ditched the best part of the dana 30, and kept the worst parts - while importing the weak links of a dana 44.

After all upgrades done, the biggest drawbacks to the dana 30 are the balljoints and lack of high steer - both of which you kept.

The weak link on a dana 44 is the lockout, and the actual hub housings themselves will swell after a lockout breaks, so you've gotta buy a new hub, bearings, etc.

He wasn't (and i am not) knocking your work, which was very well done - but you'd have done a lot better to put a d30 unit bearing into a d44.. =)

Re: Dana 34: D44 hubs & brakes on D30 Knuckle

Reid makes 30/44 knukles with high-steer built-in, using chevy spindle and ford 44 brake and hub. That is the way I am going; bought them used on this site.

Well a d30 unit bearing is too small, so that is out of the question. I wonder if another unit bearing would be plausible. At any rate, I see where you guys are coming from, but on 33s open dif I sincerely doubt I am going to blow. the hub, and as a daily driven rig, I have to say that I love the lockouts. The noise reduction itself is worth it. That has been the first I have ever heard of the hubs being the weak point on the 44

I am aware of this, but again this was an extreme budget project

A unit bearing of any kind would negate most of the reasons why you did this.

Re: Dana 34: D44 hubs & brakes on D30 Knuckle

Nice work. 'Pretty good way to get hubs and decent bearings if you have the shop to do the work.

I think the reason this hasn't been done much is because of the machine work required. While it's not extremely technical, most of us don't have the lathe and mill sitting in the garage. If you threw in the cost of having the work done at a shop, that would kind of negate the "cheap" factor.

Re: Dana 34: D44 hubs & brakes on D30 Knuckle

I really like this! What was the donor vehicle for the parts used.....spindles, caliper brackets, hub/rotor.....?
1/2 ton Ford, 78/79 Bronco?
Wonder if Chevy stuff would work.
Had a thought (and it hurt) what about opening up the knuckle bore instead of machining a step on the spindle......would make spindle replacement (if it were ever required) a lot simpler---------Hans

You pretty much got it with the parts. The reason I didn't open the knuckle is twofold: turning the spindle is really easy, and I wanted to leave as much on the knuckle as possible, especially around the hub bolts. The downside of which is as you pointed out, any replacement spindle must be turned, but again its incredibly easy given you have the equipment.

Re: Dana 34: D44 hubs & brakes on D30 Knuckle

I wonder if F250 unit bearings can be made to fit in D44 knuckles?

Most of the modern dana 60's use unit bearings. A couple of companies convert them to 5x5.5, I dont know that you could fit any in the d30 knuckle though.


...what did you think the weak point on the 44 would be? It's bigger than the dana 30 in every way except the hubs..

Why the XXXX would you want that?

Those things don't hold up well at all. I know KOH racers that have to change them after the one day race. Machined ones go for $360/each. 8x170 ones go for a tad cheaper.

Oh yeah, unit bearings suck.....

Ujoints are obviously the same..... and as I am not running ctms or anything special, I consider that the weakest link

This is great. I just finished up gathering the parts to do this with Chevey 10 Bolt parts. so I can match my Rodeo D44 Rear.
