I was driving my truck down the freeway today and it felt like a big gust of wind pushed my truck to right but there was no wind. I pulled over looked at it real quick and did not see anything weird going on. It did twice and I immediately pulled over. I was close to home so I limped it home slowly and never felt it again.

Has anyone experienced this? The road is good and smooth and there was no wind or other vehicles around. I haven't had a chance to look at yet but I'm curious what might have caused this as it had me a little scared.

The question is now this:

I tried pulling the front right hub. The outer bearing seems to be seized to the spindle. The nut and washer came off and the grease is like hard tar. I'm at point that I don't know what I should do. I also used a slide hammer attached at the wheel studs and hammered the thing to the point I pulled something in my back. Any ideas would be greatly appreciated.

This is probably not the answer you would have liked to hear:

If you were to pull the complete spindle assembly off the ball joints, could you support the hub on a press plate and press on the outer end of the spindle to push it out of the hub?

I suspect that the bearing got hot enough to seize to the shaft and replacement of the assembly may be your only option.

Even if you are able to press the the hub off the damage to the shaft may be too much save it.

Good luck!

I made hardware store run to get some 1/2 inch 20 bolt couplings and bolts so that my puller/slide hammer tool would bolt directly to the hub. Once I was able to get a solid hold on it I tightened the handle until it came off. The other side came off easy but the grease was like half set up Bondo.

I did new bearings, races, seals and front brake pads while it was apart. Just took it for test run and everything seems to be ok so far.

Just out of curiosity does anyone make a brake upgrade kit for these trucks that doesn't cost a fortune and will work with 15" wheels?

I've never been impressed with the factory brakes and since adding the extra horsepower it seems a little sketchy sometimes. The pads I put on yesterday seem worse than the old ones that were on the truck when I got it. Maybe they will break in and get a little better over time. Would upgrading the rear to disc make any difference under normal driving conditions? I could see them making a difference in a situation where you are doing a lot of braking where you might build up a lot of heat but not sure it would be worth the money for an average trip of 12 miles down the freeway.

12" rotors (what you have now) are the largest you can go with 15" wheels. You could look at aftermarket setups like Wilwood, who I think offers 4 piston calipers, but I don't think you are going to gain very much relative to the cost.

Rear discs aren't going to help much unless your problems turn up only when the truck is heavily loaded.

That's kind of what I was thinking. I have good feel at the pedal and nothing feels like it's bleeding off or anything but it seems like the brakes require some major pedal pressure. Maybe it's just me. I drive newer vehicles on a daily basis and my old c10 once a week or less on average.

Are your the originals...?

I'm not sure if they are original or not it probably wouldn't hurt to replace them though. I am hoping maybe after a while of driving they will wear in and work better. I don't think I have 2 miles on the new pads yet. It's kind of been on the back burner for a while in hopes it sells.

I swapped out my front brakes and used 74 front brakes (disc).I used the whole front engine crossmember as I did a complete resto/mod. You don't have to use the crossmember just the spindles out. Truck stops on a dime

There seems to be a lot of confusion on the 73 and up brake swap or maybe it's just me as I have never seen it done personally. I have heard people say to use the whole cross member, I have heard people say you only have to use the spindles, and I have heard people say the ball joints aren't compatible between the pre 72 trucks and the 73 and newer. I still haven't driven my truck since the day I did the wheel bearings and brake pads.

I was honestly just hoping it would sell so I can move on to the next project. Since I'm trying to sell it I really don't want to take any unnecessary risks in driving it. That's when bad things seem to happen. It's frustrating seeing it sit in the garage and not wanting to do anything to it.

I have a 1970 GMC c30 1tom with 8 lug wheels and I all so would like to go disk brakes. Been told I can swap out the whole front suspension. I hope this is correct, I think it would be easier because I could do a complete rebuild before the swap.

Welcome to Chevy Talk from West Michigan!

My son and I are doing a swap out of the whole cross member assembly on his 70 GMC and currently going through everything including cleaning, painting, and replacement of parts as necessary. We have done similar swaps on C-10's but this will be our first on an 8 lug swap out.

One difference that I have noted so far is on the 8 lug cross member taken out of a 72 3/4 ton is the extra bracing on it. Our other swaps have been C-10 to C-10 and there was no extra bracing.

With the added bracing we will have to drill the frame for the extra brace to bolt up to. I am not sure if there are any other differences which will have to be addressed.

We are hoping to have the assembled cross member ready for installation in the spring.

Will do!

The braces affect the gas line and brake line routings, but not a lot.
