Tire Bounce...

[badgerd]

Have you tried calling High Dust 4X4 in Norflok or 4Wheel Parts in Va Beach? Those are local off road shops, Hi Dust had a great rep 20 years ago before I moved north.

Both refused to do anything with “split rims” and won’t balance with the runflat installed. Supposedly there’s a truck shop that will do it but I can’t get them to answer the phone...

I had my alignment done at an industrial truck shop, as they were more comfortable with large split rims. Local garages that provide to Jeepers are not as equipped for heavy-AWD stuff like ours. Maybe a few calls to tractor-trailer servicers?

I found a small shop today that is willing to do it, they work on RVs and odd stuff. They can’t do it for 2 weeks (only open a couple hours a day because COVID), but that gives me time to check out some other things before taking it in.

NOT split rims.

Two piece military bolt together, double bead lock. This will totally confuse them.

Call them "split rim" and most tire shop are going to turn and run. CAMO

Also ensure the shocks are not bad. [EDIT - I see you already replaced.}

Fair enough, but similar enough as well for shops to shy away in my own experience.

You say "SPLIT RIM" and old guys begin to shake... living facts and stories of rings flying thru the air, tearing a hole in the roof or worst, someone getting killed. (history for the newbies, not us old stinkers)

As for the HumV 2 piece, combat, double bead lock rim... Kid can't find it in the pricing book, what the heck is it off of? HumV... WOW. Looks like a lot of work, not set up to do it, won't fit machine... and don't forget to tell them there's another tire in the tire. LOL

Yes, Simple tire, serious business. Follow the rules / safety ALL the time. A lot of air in those fat tires to launch one to the moon.

I'am not crazy about the messing with HumV tires... But it is a part of the hobby. PITA for the first one. Now almost fun to see how quick to swap out a tire, fix a leak, save a buck, right back on the road.

Stay safe, know your rig, play by the rules, CAMO

I'm glad I'm not totally losing my mind thinking there was something easy I was missing. All of the parts replaced were worn and ready for replacement, so I wasn't throwing parts at it, but beyond this I might be! I have a dial indiacator and will check the runout of the wheel on the hub and see how that looks then check the hub itself. When I did the spindle nut I checked the spindle for damage, but anything is possible with a 23 year old rig with only one year of history on it (previous owner inclueded some parts and replaced the IP, but thats all I know).

When I find my clamp pliers again I'll do the boots on the CV and inspect while it's out. I have checked the control arms for cracks/damage as well as the spring.

My last ditch will be to velcro a gopro somewhere to see what's actually happening... It only happens at speed so it'd be hilarious to stick my head under the truck going down the highway!

Ummm.. 1987,,, That would be a 33 year old rig, not 23

It’s that new math they’re teaching our kids in school. I before E except after 3, and stuff like that.

I blame Gloria Steinem, Jimmy Carter and those darned hippies. It also didn’t help when Bob Dylan went electric.

I took my M998 to a large 4x4 shop for a balance. I wanted weights attached to the wheel. He called and said the wheel/tire started to shake his balance machine so much he had to stop. Ended up putting beads in the tires. Not impressed so far with beads. Feels OK then next time I get a bad shake then it calms down. Two piece wheels blow.

Might try bubble balance. Cheap and easy. Sounds serious out of round??

Don't know what you have for tires BUT if surplus and OLD as found on surplus truck sold...anything could be wack. I see them sitting flat here in CA. Hot, cold, bone dry and age can't be good. Most 10 years plus old and that could be a law breaker on the hiway? Look at the pictures on the Planet site and one can see where they sat in the mud, flat. Air em up, move em out.

Very surprised they can sell them that way and it hasn't come back to bite them. Then again... it's a used car, CAMO

After my own attempt to align (which was close) I took it to a shop that would put it on the rack. An hour later and a little tweaking and toe is set properly AND the bounce has gone away (or 90%, the rest is tires and that's the next fight).

Drives much better than 3 weeks ago!

They checked the camber at the same time, +1 on the left side and 0 on the right, both front and back. No shims at all in the rear. Find that strange but thats another fight for another day.

Centramatics will go back on this week and see how that does while trying to get the time to get them balanced...

 

[TOBASH]

Have you tried allignment?

also...

I love centrimatics BUT did you swap the two front centrimantics to see if maybe one is bad?

I wonder who advised alignment and centrimatics?

Where can I find a bubble balancer that fits the 4 1/2” hub diameter of the HMMWV wheels? I have only found them with 4” max diameter. I’d love to DIY balance if I could WITHOUT centramatics...

Asking me where?? Google it. Being the nicest guy on the WWW I did it for you > https://www.bendpak.com/wheel-servi...0B30ZR0lJhvJRr1AzKpuTx1r_n1BfZDBoC0B0QAvD_BwE

For oil changes... you get to do that yourself, CAMO

Perhaps because it was not in JC $hitney or FleaBay or Scamazon?
