Low speed death wooble

so after I got a flow master 40 put on my truck started doing strange things like from 25-35 the whole truck shakes like I can watch the hood shake and the radio will come out of the dash all kinds of shit and the from about 55-90 it has a hm viberation u can feel in the seat. I took it to the guy and he said it wasn't the muffler so Idk if did something or this is just a coincidence or what but I changed my spark plugs that didn't fix it I'm wondering if it's a wheel bearing but in input would be helpful

 

Did this happen immediately after you had the new muffler put in? Maybe they messed something up when lifting it. Check the driveshaft?

 

Can you feel the vibration in the steering wheel? If yes I would suspect the front wheel balance.

 

I wouldn't say I can feel it in the steering wheel but it did happen right after the muffler like the drive home. But I've felt the drive shaft and the doesn't have that much play and I think it would do it all the time but it only shakes the bad when I'm on the gas like if I don't give it gas at those speeds it rides fine

 

I can also hear like a high pitch squeak at low speeds but only sometimes my money is on the wheel bearings but not sure

 

It only does it when you give it gas ( place a load on the drive line ) and the high pitch squeak at low speeds suggest a universal joint. Feeling the drive shaft installed isn't going to tell you anything. To check the universal joints you have to pull the drive shaft.

If one is bad replace them all.

 

Would that make the whole car shake like it does?

 

Yes. You would feel it more in the seat as the entire vehicle shakes due to the driveshaft vibration.

I would check it sooner than later because if the universal joint lets go at highway speeds it could really suck!

Any update????

 

How about some updates.

 

$2400 later everything was fixed. I'm not sure if the prerunners aren't built for as much durability as the 4x4 but my thought if u put trd offroad on the side of a truck it should be able to handle some offroad use. So the problems were: the truck needed new u joints mud was caked up in them and I clean pretty throughly but obviously not well enough, the brakes had mud in the slots of the rotor and I think there were wrapped and both front wheel bearings were bad and had to be replaced, and then the Evap sensor had dirt in it causing that to turn the check engine light on. Now I have buddy's that have 4x4 Tacomas and other prerunner and I've seen them push there trucks a lot harder than I have and I clean a lot more than them so I'm wondering why my truck couldn't handle this condsering it's TRD OR rugged trail edition but it does have 195k miles

 

Thank you all for the suggestions you were all right

 

Mud breaks shit man. If you gonna abuse the truck you have to be ready to pay for the repairs.

 

Death wobble is a real term that and it doesn't happen to IFS trucks. Just sayin.

 

I'm sorry I didn't have the proper terms I just tried to describe it best as I could and it looked like most ppl understood sorry for not being technical

 

What's a wooble?
