Got the bump steer?.... (edit: juts brakes locking up I found out)

Anothwr posting had this video i have exactly same issue on my 2013 DoubleCab

https://www.tundras.com/threads/2013-dodge-ram-3500-death-wobble.2522/

It's got a 3/1 lvl on it, 35's, and been aligned TWICE already. Had the wheels balanced multiple times .

Everything is perfect . And then like every 3 weeks..... I'm driving and all is fine .and then I start to get a little vibration . 2-4 seconds later I'm flapping over the entire road and have to pull over (pressing the brakes makes it even worse). I don't even know what to do at this point.... Suspension is all torqued. Wheels balanced. Alignment done .even went to Toyota Dealership for that already. Just happened yesterday to my dad when he borrowed it. Almost crashed .

 

Never experienced it but CB shackles and Drive shaft spacers should take care of it. Talk to David @Coachbuilder1 about it.

 

Do you have the print-out from your alignment? Post it if you do. I’m curious about caster.

Stock UCA’s still?

 

@landphil yes stock UCA's. An offroaof shop said I should be fine with them because I just drive on the highway .



I asked the dealers about the numbers .They said this is the closest they will be able to get . Was gonna go tomorrow to an actual off-road shop and see what they say about that though, because over phone he said they will prob be able to get it in spec.

 

@csuviper so that posting above with the video . That's how bad my truck gets thrown around. Like it's bad . Would bump steer be that bad?

 

This sounds serious. Hope you can rectify this situation easily.

 

Sub’d

 

I thought the post said death bounce for some reason oops

 

Post some photos of your front suspension.

 

Death wobble is a by product of a style of suspension used on heavy duty trucks, and some Jeeps. Nothing close to what we have. In your case I would suspect you have a bad tire, broken belt, whatever. You hit a bump, sets the tire out of wack, and wobble. Rotate, figure it out, particularly dangerous during the heat of summer.

 

Like someone above said. lift the fronts off the ground then push and pull against the top of the tire. My guess is something is worn out also.

 

Have you considered possibly the brakes?

 

@GiantsFanDan I'll get some pics tomorrow.

@Masher59 my trucks got 55k on it. And about 4k with the leveling kit... All highway and city.... and about 10 minutes of beach driving .... i hope nothing wore out this soon...

@Vizsla it's definitely not the tires because I've had it balanced, alignment, got new Toyo A/T's, and rebalanced again and alignment. And less than a week in, it happens again.

@csuviper I've tried that already. Almost shook the truck off the jack and nothing.... That's what has me puzzled the most..... And when I try to recreate it on purpose, there's nothing...

@ColoradoTJ well thanks man! I guess I'll change topic to bump steer and research some reasonable UCA's now (was kinda avoiding that lol)

@15whtrd I have.... But there didn't seem to be anything off about them when I checked....

 

Wasn't the bump steer i guess . Something to do with my brakes. Had it happen today. And then it kinda smoothed up but I noticed more resistance to driving. Stopped on a red light . It turned green, my truck wouldn't budge .I added about a half throttle (ya prob shouldn't have but wasn't a good road to stand on) to get it moving to cross the intersection and pull over to on other side..... Caused my brakes to smoke up. After walking around kicking tires for bout half hour cuz it was midnight and I had no way to move the truck, got back in and it WAS ALL GOOD!!!! So I set out to recreate the problem. I went about 30 and kicked the brake pedal enough to jerk the car and it happened again. So at least I know how to make it happen to be and to trouble and get somewhere with it now. So it wasn't the suspension at all coulda saved me couple hundred if I find out earlier lol

 

I think you have dragging pad or sticking caliper. At this point you probably replace. Hopefully you don’t have to replace the calipers. At a minimum you should disassemble them and check for any abnormal wear on the slides and pins. Lube everything up and put back together. Make sure the surface that the rotors are being mounted to is completely clean and smooth. I put a small amount of caliper grease on the backside of my rotor mounting surface. A very thin layer. This also helps him to come off easier next time.

 

Casters of 4 or more are the best for any Tundra running with a lift, and or oversized wheels/tires. Plus your UCAs may be too small for your setup.

 

It’s his brakes though

 

@trdprobped17 yeah I just got new SPC UCA's delivered last night. Putting them on this week when I get the chance.

@15whtrd I probably should have mentioned..... It was all 4 wheels smoking and it was pretty bad... My friend thought they ca ght on fire that's how bad it smoked. I guess it was kinda dragging and I didn't notice until it started to seriously slow the car, and by then they got very hot.

 

Wow, all four wheels?? Either you were running it in the Indy 500, causing it to smoke like that or you have some serious brake/wheel binding problems. Sorry to hear that bro!

 

@trdprobped17 on bright side, I know what it is now, and don't replace the entire suspension

 

Ok, cool. Do you think that you could get the repairs done by Toyota under some type of warranty or vehicle malfunction? It’s worth the try. All they can say is no.

 

All 4tires smoking? That's BA drifting a truck in 4WD.

 

seconded. either hydraulic system or the computer is activating the traction control somewhere causing the lockups upstream somewhere.. try to have a video recorded of it doing it. i know it might be difficult but best to try to get it on video so you can show a tech.

 

Well true TJ. I must have spaced it for a minute or so.
