Can you? laugh.gif

Am I the only one that seems to have never found any kit for anything that didn't need some of "I think I can do it better" modification?

Rear fun bags finally came in for the beast last week. Install instructions here: http://www.firestoneip.com/site-resources/...lation/2080.pdf

First of all I didn't order the correct kit. Can't - not enough clearence between the tire and frame for the 'correct' application - that they call under 10.000 Lb GVW, so I ordered the motorhome kit. Mounting location (under frame instead of outboard) more suitable for me, and I figured it orta be a 'heavier' kit too.

Quick eyeball and hand fit (not going to really start before Saturday) just to make sure I was in the right game says they'll fit where they need to go - barely but almost by luck. Which is odd, because the P-30 Class A motorhome uses the same axle tubes and shock mounts as mine - only difference is duallies vs single wheel, and the spring U bolts and bracket are inverted on the duallies although the pieces are the same.

Just had a smoke and went over the install instructions and checked the hardware bag against the list - prudence is fair. Everything is there.

Only two obvious 'must' deviations are that I'm going to have to punch out drill the frame after punching out the rivets (snubber brackets are riveted not bolted - indeed I've never seen GM use bolts on them), and lifting is definately going to be required to do that.

The brake hard line across the axle tube will also need to be moved. this is mentioned, but I have no intention of using nylon cable ties to hold the reroute. I may be staisfied with hose clamps, or I may tack some new bendy brackets (the oem uses small tabs of steel that are simpy bent over the lines to secure them) to the axle housing. To be determined.

But what's bugging me is the brackets that mount the fun bag to the axle tube.

First, the upper bracket appears to be 'universal'. The square design would in theory fit tubes between 2-1/2 - 4" the range of axle tubes used by GM from 10 to 14 bolt IIRC. This would save them stamping and bending semicircular upper clamp shells for each axle. IF they were absolutely and securely fastened, I don't see this as a major issue, but this is the thing:

The lower axle straps are IMO not only too thin, but also are for a much larger radius that my axle tube - maybe 6" (there is no such animal by the way as far as I can remember in this class - axles that heavy were square tube castings, with the exception of some old Eatons used in 5 tons)

As well, the straps are quite light material wise - formed from a bit thinner than 3/16" mild flat stock.

Of coure their purpose is to stop the bag from falling off the axle at droop - but still they just seem too flimsy to be doing suspension duty of any kind. I can see them deforming rather quickly allowing the upper bracket to start walking around the axle tube until the 4 contact points get worn, pummeled, or wear into the tube.

Seems a section of 6 x 6 x 3/16" rectangular tube would be in order - sliced and cut to make a pair of proper round brackets (think a very large very wide muffler clamp ) to sit on the axle, fastened with U bolts and nuts.

Actually I might check to see if muffler clamps are in fact made in that size, because then it would simply be a matter of welding a pair to a square 1/4" plate - far less work than fabbing brackets from scratch: drilling 6 holes per side and a bit of non critical welding.

In the end though, can't help feeling like it's just 'me' - just can't follow the damned instructions like it would kill me if I did laugh.gif . That's almost a bit depressing, and the more I think about it - I never could. Always had to sub out that ungraded bolt for a grade 8, or cut this, or add that. Recently even had to add a grommet to center the contact spring (which tendede to flop over and spit off the positive contact) in a flashlight I bought for a few bucks. Curse or gift i ask?

Well ...

1 - Been told I'm not allowed to cut and paste with real women.

2 - If ya just gotta do it to your ride - uh, vehicle - ya gonna go T&A or http://trucknutz.com/ ? laugh.gif

(fun bags indeed. User selectable ride comfort / bag size via standard schrader fitting - 4 million years of evolution never developed that kind of convenience biggrin.gif )

I was snagged into this post simply like Tim with the absorbing of fun bags.

I usually buy components with the express idea of modding them to suit my purposes. The only time I leave them as is is for exact OEM replacement.
My latest equipment purchase is a good example...I bought a $150 bench sandblasting cabinet from Cambodian Tired. 3 weeks later, it's installed as a floor machine, with full outside exhaust & completely reworked abrasive collection system. The new system requires only about 1/4 of the abrasive of the original, & separates out chunks & dust besides. The lower abrasive amount makes it practical to use silicon carbide in with the sand for faster cutting.

When it comes to vehicle mods, I plan first, then look for parts that do what I need. If they are made, fine. If not, then I mod the closest product...to my standards. I don't believe in planned lifespans...everything I do is done with an eye towards forever. I also don't believe in having to fix anything more than once.

Also, for relevant content...

I am rather insistent on following the directions. I despise that moment of "Well how do I... crap, those had to go on *first*, now I have to take these one apart again to get the other ones in there."

But I do love modding things so they perfectly fit my exact use. I'd never do it with anything new, but then, I rarely buy anything new anyway. If I get something used I consider it "rescued" and have no guilt about performing surgery on it.

Also once or twice, thing like this:
