Air bump placement

[Buddha]

What do you think of the placement?


I took an old rear bump stop, cut it down for a striking plate and then angled the air bump in a bit. The stop is just touching the rubber on the plate at the back.

Thanks for your input.

What about your shock? Looks like it will be in the way.

i forsee the issues with the striker and ubolts

Even with the axle cycling to the rear of the truck?

The shock mount as been moved to the knuckle.

your going to hate me for saying this, but the only real way to find out is to pull the pack apart, leave the main leaf, flip the lower leaves, put pack back together, cycle the suspension.

[Buddha]

I totally agree that I should have done it that way from the get go, but time would not allow. I'm going to try and ramp it tomorrow to see how it does. Thanks for the tip though.

ive got a few ideas in my head, ill see if i can draw something up or figure a way to explain it for ya

[Buddha]

That would be great. Thanks.

[mobil1syn]

you got leaves, whats this for?

[Buddha]

I was going through shackle bushings all the time, plus the steering was very sloppy. The trac bar has cleared all that up.

check back tomorrow and i should be able to get a dwg together with my idea or something for ya

[Buddha]

Will do. I will try to flex it out after work with some pics.

Looks good. That's about where mine hit on the rear.
Be prepared for the rubber pad to have a hole knocked in it soon. I've even cut pads out of semi truck tire tread and they still wear fairly quickly. I guess I could change the end of the air bumb but then it would just wear out instead of the pad. Then again you can just get use to the noise.

[Buddha]

Thanks Dick. I am going to try and flex it out, mall style today. With the track bar there shouldn't be a whole lot of lateral movement so I "think" it will be okay. I guess I'll find out.

[Dickfoster]

Of course you should cycle it completely before you finish weld. Not doing so is just asking for trouble.
Try to do it so you can get a cut off wheel in there to remove the buckets if at all possible. I know it's really tight in there but think about it just the same.
Also check to see if you can still remove the bump with a full nitrogen charge by jacking up the chassis. On my rear with the strike plates like you have I need to remove the strike plates but that beats needing to recharge the bumps. Unless you happen to have your own nitrogen setup.
Oh yeah that reminds me, pay attention to access for the sharader valves too.

[Buddha]

I think on of the problems I may have is that the shocks are mounted on the inside of the hoop. When I mocked one up last night there is only enough room to put my pinky finger between the bucket and the shock. I think I will also have to out board the top mounts of the shock. With my bumps, all you have to do is take out the little snap ring, loosen the buckets and they will slide out the top for easy removal.

Thanks again.

Was it the bucket or the bolts for the bucket? You could always turn the bucket towards the cab to gain some clearance if it was the bolts.

By the way I was right.

[Buddha]

Yes, you were right. I thought moving the lower mount would fix my problem.

[mobil1syn]

so heres a pic of what i am going to do when i mount my bumps ...

basically your turning your ubolt plate into a flat surface of a piece of delrin so you dont have metal to metal contact.

[Buddha]

Sweet!!! Thanks for the drawing. That is a perfect solution.

Tim

[mobil1syn]

just remember to make sure you can get a socket on the nuts with the bracing acrossed the top.

[Dickfoster]

The bumbs will probably beat the pee water out of delrin over time. I tried a lot of stuff before I did patches of tire tread. Damn that stuff sure stinks when you cut it. Best to back the plastic pads up with some Al tooling plate or something too. Your drawing could be saying that but I just don't see it without some annotation.
I just set the strike plate on top of the spring mount nuts along with some additional flat washers that then added some nyloks on top.

[Dickfoster]

Now there's something else to think about. Nothing is easy is it? LOL

[mobil1syn]

when i do my setup ill be using some 1/2" delrin/cuttingboard/whateveryouwanttocallit and considering it a consumable item and more than likely a custom machine bump striker.

maybe this will clarify what im getting at. this would be welded together as one piece. the plastic would then be mounted with machine screws at the corners into the yellow tabs. the red in the original drawing is the delrin
