Flex Issue...

[Ol'Blue]

So,

This is the set up in the rear, 906's with 4th Gen OEM length shock in the rear, and NO sway bar at all in a 99 Limited 4x4 with e-Locker.

So today I pull off in this ditch that I new would flex out my rear end pretty good. Well I was not expecting the loud pop sound that I hear as I was traversing this thing. Same thing happened when I came out of it.

Well I got home just down the road and looked at the truck. I though I might of got into the gas take because [MENTION=91297]Kraze[/MENTION] had this same issue with his set up. Well guess what, YEP!!!!! The only thing strange about this is that it is hitting right at the rear of the drive line and getting into the u-joint. That is where the rub make it. I looked at the gas take skid and sure enough on the rear of it on the right side it had an really good bend in the skid.

So, What do I do about this issue. I really do not want to F up my drive line at the U-Joint. Around hear in MO now you need a gas tank skid.

Should I just pound it back in for starters? Should I try and cut part of it out?

I will post pictures in the morning so you all can see this.

I know she flexes but really....

I would pound it in as close to the tank as you can. It'll probably happen again if you pull it out, and cutting that section out will screw up the stiffness at that part of the skid since you want the skid to be as deep as possible.

Also be careful since you can break the stock upper links with a lot of flex which [MENTION=91297]Kraze[/MENTION] and I have had happen.

I was thinking about just having a set in the truck on stand by for that issue. I know about his issue. I found the link for him,lol. 8 bucks at a wrecking yard! I picked up a set of jimmy bump stops today and am thinking about putting them on to maybe help out. They will just be longer than the stock ones on the 4runner.

I have 8-wraps in the rear and my driveshaft has made friends with the gas tank skid too. I haven't done anything yet, but it looks like I can probably alter the tank skid just enough with a BFH that they shouldn't actually contact.

Anyone make stronger upper links that are good quality? I know Sonoran makes lower ones but haven't seen much talk about upper ones.

ToyTec makes adjustable upper arms.

I have 7 wraps and I also hit my tank, but it no on the u joint, just he shaft to tank so when Im flexing out my truck squeals like crazy. My buddy says it sounds like a Sherman Tank flexing over the rocks, LOL.

I do have SS lowered bump stops which I can say help a lot. Also stops your rear shock from blowing out when over flexing. I have not broken anything yet and beat the hell out of my truck on the trail.

Anyone used them? Any good? Any feedback on how they compare and how the bushings compare and hold up over stock rubber? I'm trying to limit use of non stock rubber bushings on truck to try to prevent squeaking issues.

Thanks.

I went with the hammer method. It's a quick way to make the clearance for now. The strength might be lessened by thinning out the metal in that location, but I doubt the skid will take a hit in that location. Plus I rolled the ends after smashing it in, so if it does make contact it will not dig into the tank.

Here's a link to the page in my build to show you what I did...http://www.toyota-4runner.org/3rd-gen-t4rs/132212-dirtbike250xs-build-thread-5.html

Ive had a set in for little over 1 year and no issues/noises. I bought them to fix the pinion angle after lifting the rear.

Cool. Thanks for the feedback. I'll look at them if I decide to upgrade my uppers at some point.

Sounds good. I always like the BFH rule any how. It is fun that way. Going to throw the longer pump stops on and see if that helps out at all.
