why does my truck wobble at certain speeds? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

roughedup72 · 06-14-2007, 09:19 PM

I've noticed that every since I've owned my truck at speeds between 45 and 53 my truck wobbles, Like a dog thats shaking water off of it. It doesn't matter if I am on the gas or coasting, In gear or nuetral. Any Ideas??

GREASEMONKEY72 · 06-14-2007, 09:28 PM

well right now my truck wobbles between 15-35mph because of a cupped tire

but it could be tires out of balance/cupped, driveline, trans

71tahoe · 06-14-2007, 09:29 PM

This would be my easiest to most difficult repair list.

Tires out of balance.
Bent wheel.
U-joints.
Tie rods.
Bent driveshaft.
Ball joints.

71tahoe · 06-14-2007, 09:39 PM

LWB?

also check the carrier bearing.

Not to make fun, but your description really really makes me want to see that!

JHART · 06-14-2007, 10:00 PM

I was just about to say carrier bearing ....

Mine was the same way at around 2000 rpms ... come to find out the carrier bearing was off a bit. Needed to be adjusted .... go figure i didnt think you could align those things.

honestly so would it, but i dont want anybody else to drive my truck

roughedup72 · 06-14-2007, 11:34 PM

HA! I couldnt't come up with any other description. But I sware thats the way it seems. I wonder if people riding behind me thinks " is that truck trying to shake light a dog or am I just seeing things"
I just had the drive shaft balanced and new carrier bearing put on along with new u-joints. Tranny new,tires new no cups but that doesnt mean there not out of balance seeing as how I had the morrons over at sams club mount them and balance them,( bad experiences in the past). Could be a bent rim or carrier bearing needs adjusting or ball joints and tie rods. Thanks for the help and I will check these as soon as I can.

GREASEMONKEY72 · 06-14-2007, 11:43 PM

before i had this cupped tire problem my truck would move a bit and i had everything checked out, the tranny shop said everything is good, i balanced the wheels myself, the trans is fine, the wheels arent bent, then i noticed my brothers 05 f250 does it and so does my bro inlaws 95 nissan 4x4 hardbody, so its just a truck thing

68chevy68 · 06-15-2007, 12:00 AM

When I picked up my 77, it wobbled for a block and I took It back, changed tires and it drove fine after that. The tires had flat spots from sitting so long. It sit for like 7 years on concrete.

jhow66 · 06-15-2007, 12:03 AM

I have two trucks and they run smooth at any speed. ('71 & '65)

A.P. · 06-15-2007, 05:20 AM

Had a car that did the same thing but at 55 to 65 mph. It turned out to be the shock absorber, front. Good luck.

Blazer1970 · 06-15-2007, 06:30 AM

bad tire

cdowns · 06-15-2007, 06:31 AM

my first guess would be a combination of front suspension pieces// personally if i go into the front suspension i do everything i find in the long run its time and cost effective compared to a suspension collapsing at speed

krue · 06-15-2007, 07:43 AM

Tires are my guess.

Mudder · 06-15-2007, 09:11 AM

I had a '63 at slower speeds that would shimmy so bad you couldn't hold the steering wheel. At the time noone could figure out why. An old friend added a steering stablizer and it never did it again. Never did figure out why it was doing it tho.

**Ricks1971** · 06-15-2007, 09:54 AM

TOO MUCH BEER!

68GMC454 · 06-15-2007, 12:25 PM

i would go have your tires rebalanced..after crawling under it to see if anything is in bad shape or missing...then the shocks...i got to do this on the ol ladys car one day,,but i hate working on a ferd, so i put it off....

CrashEd · 06-15-2007, 12:38 PM

You probably have loss upper A frame bushings and the camber caster is off making the front end have a little play. Or somthing else loss. Need to go get it lined up and thay will check everything.

sorry I had to

70GMC_BOB · 06-15-2007, 02:01 PM

I don't remeber my truck wobbling, but then again I am waiting to rebuild the mufed uf gm goodwrench engine My dad and I rebuilt last summer that has no oil pressure! I do remember in my 71 suburban that I had that similar problem , but discovered it was my driveline u-joints & carrier bearing.

If you are having vandilism problems, I would suggest a larg yellow jackets nest under the hood like I found on my truck. It kep everyone out!! LOL!

Bunk · 06-15-2007, 07:02 PM

I would have your front end checked out, including the steering box. If it is not ajusted right it could cause this problem due to to much play.

crm318 · 06-15-2007, 10:53 PM

have you hit any curbs? one time i hit a curb at 35 and after that, the truck wobbled like you are saying. i lifted the truck and there was a huge blister bulging out of the tire that hit the curb. got a new one and that solved it.

**68 Stepside** · 06-15-2007, 11:02 PM

I had a bad pitman arm when my truck did that. Please check everything in your front end to be sure it's not a linkage problem.
