Violent Shake when i hit a bump

Recommended Posts

Hi Guys,This started about a week ago i was driving downt he road when i hit a significant bump. Immediately my truck started to shake, up and down, like it was bouncing down the road. I can to a stop and check out everything, i didnt see anything out of the ordinary so i went on my way. When i started rolling again the shake was gone. The episodes have been becoming more frequent it happened 2 today in a 10 mile drive. Has anyone one see this or ran into this? i took it to the shop today and they told me everything seemed tight. But i know something is seriously wrong.

Yes the videos in that thread are a perfect example of what is happening to me! Thanks for the info! which component is most likely at fault? or does it differ greatly?

The first thing to check is your trac bar. The ball end seems to be the main wear point. Just remember, when you check everything else all it takes is a little movement in the trac bar, plus a little in a tie rod, plus a little in a ball joint, plus......well, you can see how it all adds up.

I'm trying to find it, but I read something not too long ago that discussed about a cheap fix that would eliminate the death wobble. Because even if you replace the bad part(s), you will still suffer from it again. Alot of it, IIRC, said that its due to the fact that one end of the track bar is a bushing, but the other end is a joint. A joint that is eccentric. There is some sort of sleeve deal that you install on it that will fix it.Give me a little and I will try and find the article on it. I could have sworn it was on Geno's garage...

You can do a lot of good by putting a steering box brace on it. There are numerous different brands out there. I have a PSC and it has been great. I know BD makes one also. Sent from my iPhone using Tapatalk - now Free

My jeep started doing that crap. It got worse and worse until the stuff on the floor was on the dash. Oddly enough, rotating the tires fixed it. Was doing it 10 times a day, hasn't done it for a month now since rotating. No clue what the deal is. It was the passenger side front.

Lukes link makes a good fix for the trac bar, spendy but it changes it so once you have their track bar you can replace the bushings on it for a fraction of the cost. (genos garage has it and a couple different variations) Also have heard people who have trouble with this are running worn out tires or load range D, a buddy bought a brand new set for his 97 and his truck did it terribly. might explain the issue being fixed on the heap ISX ;)

I had load range D tires that were very worn out, I just replaced them on wed and haven't had any issues since we will see if this fixes it permanently or just a temporary fix. Sent from my RM-820_nam_att_100 using Tapatalk

So the tires have made it much better but it happened once the other day so I will follow up once I test the steering components update: I have found some info on genos garage for anyone else dealing with this problem. Follow this link and there is some info at the top of the page along with a few more links. http://www.genosgarage.com/Steering-and-Suspension/departments/140/ Sent from my RM-820_nam_att_100 using Tapatalk
