New here thanks for having me 86bluek10 with k20 axle 6 inch BDS lift 37in tires on 20 rims but changing to a 16 in rim soon

[86bluek10]

Hey all,
I have a 1986 SWB K10 6 inch BDS lift 37 in tires with 3/4ton axle swap I believe 411 gears. driving at any speed, when I accelerate the truck shakes like a wild banchee.. I give it more gas then it goes away. It does this at almost any speed. the first thought was u joints, nope they are good. the off road shop said driveline was good. Any thoughts?? Thanks

Howdy!

That's a mighty long thread title too! I'd be inclined to think there's an issue with the driveline angles.

 

[86bluek10]

I asked the local offroad shop who installed the BDS lift they assured me the angles of driveline are correct. Lowered the t case As well.

Do you feel the shake more in the seat (rear axle) or thru the steering wheel (front axle).

Ball joints good? Steering box tight on the frame and frame not cracked?

You might look at a 17" wheel instead of a 16" to change the subject to you looking at new wheels. Lots more selection in a 17 vs a 16 nowadays.

Steering box is tight, unfortunately i feel the shake everywhere. Front end was gone thru and all new u joints, shop said ball joints are good.

Ya I'm trying to find some steelies with dog dish caps but in a deep dish. If I can't find what I want to do I'll have to go 17 inch, yes you are correct way more options for wheels and tires.

Are the tires balanced? Or maybe one is bent??

 

[86bluek10]

That is a good possibility they are pretty poor condition.

Another member had a similar problem. Check your drums and rotors. Might a broken one. That's what the other guy found.

 

[86bluek10]

Thanks I will check them.

You might have a tire separating if they're in poor condition.

Process of elimination.."shop" has deemed u-joints, drive line angles, Ball joints, etc. are fine.
Concentrate on tires/wheels, brakes..inspect for uneven tire wear, hot spots on rotor, etc.
Good luck.
