It appears ARB has fixed the bumper "tipping" issue?

[R_Lefebvre]

I got a new "fresh off the boat" ARB bumper for my 04 last weekend (yeah yeah, whatever) and I have been installing it slowly over the past week. I noticed what appears to be a significant difference between it, and the photos I've seen of other ARB installs.

I have photos I'll post up later. But basically, my crush cans have extra material (tabs) which extend backwards behind the factory mounting bolts on the the horizontal surface of the frame. First you attach the cans using the factory horizontal bolts, and get everything lined up as you like. While playing with this, it's immediately obvious why the ARB bumper tip.

However now, after you finish getting everything lined up, you get under there with an extra long drill bit, and you drill two holes on each frame. Up through the bottom tab, both the bottom and top surface of the frame, and up through the top tab. Then install 2 long bolts *each side*.

This essentially PINS the crush cans to the frame in the vertical direction. They CANNOT move. It would appear to be more secure than even the RTE system.

After you mount the bumper to the crush cans using the 3 bolts on each side, you also drill it in a 4th location, pinning the bumper to the cans.

This appears to be totally new? I'd never seen this on any other bumper install pics before.

Have them on the used ARB that I put on my wifes D2. Nothing new.

I just installed an RTE and was planning on utilizing something similar as I have had horrible problems with my ARB moving on me and I don't wanna just weld it to the frame like some I know have done.

weld it, you know you want to. Plus, its faster than bolting it on.

I did a install on a 03 a couple years ago and it had the exact same system.

the problem is that the crush cans still are the stressed member and thats where the flexing comes from.

this person had no plan of ever going off road they just wanted something that looked more the land rover part so I am sure they will always be happy but I sure wouldent want a bendable member in my bumper mount.

glad your happy with your bumper

Well shit, what's going on? I've seen photos of crush cans without the extra wings, and read reports that the tipping problem was due to the cans rotating on the frame ends?

I thought it wasn't the crush cans bending at all. Hrmph... It's so hard to get good info.

 

[DennyDoler]

You may be correct about the crush can not moving, but the other four bolts that attach them to the bumper (which are a complete pain to get to after you mount you're winch into the box) have plenty of movement when you pull on the recovery points under the bumper.

How the fuck do you install a bumper slowly over a week? I am all of two left thumbs and it took me about 20 minutes to install my bumper.

 

[R_Lefebvre]

I guess I'm more careful than you.m I didn't use a chainsaw to get the original off, etc...

Denny, did you drill the other hole and pin it on the forward mounts (the ones by the winch). On those bolts near the winch, I have 3 bolts each side, plus the pinning bolt for 4 on each side.

Sorry R, I had the same exact question when I saw your post.

so hard to get good info? Someone mentions in EVERY discoweb ARB bumper post that these things rotate!!! It's you claiming that it was fixed that is the bad info

huh...just about everyone's who has had a issue stated that the problem was the crush cans...who said that they changed the design and fixed the problem

Don't you remember? He's an "engineer". The simple becomes complex and the obvious becomes mired in differential equations.

Sorry I'm very busy, work on it about an hour a night. If you guys are that fast, good for you.

Yeah, I've heard they rotate. I got that part. I also read that it wasn't the cans bending, but the two-bolt mounting scheme rotating. Thought the extra bolts fixed it. Guess that's all wrong.

I even made a post trying to get to the heart of the matter, but of course that degenerated into a thread about where I drive or whatever. I'm used to a much higher level of discussion with cars, so I'm kinda left guessing with this thing.

huh...just about everyone's who has had a issue stated that the problem was the crush cans...who said that they changed the design and fixed the problem

I thought it was the cans rotating on the mountings. I've never seen a picture of a bent can.

Anyway, whatever... it's done now. I guess I'll just see what happens from here.

I just installed an RTE and was planning on utilizing something similar as I have had horrible problems with my ARB moving on me and I don't wanna just weld it to the frame like some I know have done.

Well, hang on a sec now. If the problem is the cans bending, then why bother welding it?

:rofl: :smilelol:

If they wanted to solve the problem, do like RTE did and have you remove the crush cans. I can't see how mounting a winch bumper to DII crush cans could be a very good idea.

Maybe Kevin Willey could explain it to me.

Which was told to the engineerin' genius many times as to the solution to keep it from rotating...


but we give bad info because when a shitload of uneducated redneck's tell's an engineerin' type that the bumper is shit, we can't be right. That his will be better because of all his engineerin' experience...


shithead, how many people that have bought, installed, bent and dumped them does it take for you to get the point that they are a great mall crawler bumper, but are useless off-road...


but we ain't got no engineerin' experience.

 

[R_Lefebvre]

Alright, whatever. I bought it knowing the risk, was surprised to think they fixed the problem. Thought I'd share it here and/or ask the question to be sure. Of course now it turns into another bashing thread.

Guess not. Problem remains. DWeb life goes on.

Hey! I will have you know that I am an EDUMACATED redneck engineering type (even though former environmental engineers aren't considered to be "Real" engineers, I guess I need to buy a train!).:smilelol:

me tu...i'm edumacted in engineerin..but double E's can't fix'um them ther cars u know...

Ditto. :rofl: Must be those new crush cans with wings...
