95 yukon shaking

[DIAZ]

I was wondering if anyone has encountered this problem, I have a 95 yukon 4wd and anythime I go 70 or higher my whole front end shakes, dash steering wheel, gas peddle, and the faster I go the worst it shakes. I've changed inner and outer tie rods, upper and lower ball joints, drag link, 4 brand new shocks, pitman arm, idle arm, upper and lower control arm bushings, sway bar bushings, sway bar links, body mounts, drive shaft, u joints and also the gear box. I had to replace my rear leaf springs with new ones. I've had 4 sets of different tires on also and it stills does the same thing. I'm seriously running out of options on why my yukon shakes. If I missed anything let me know. Thanks.

Are you're tires properly balanced? could be a bent wheel. But I would start by checking front two wheel bearings.

 

[sumo]

any resolve for this? How about rotating tires front to rear. See if that changes.

 

[Gzes]

Im guessing hub bearings. If bot then get the tires balanced. Could have a slightky bent wheel check em all good and if so get a replacement from jy or wherever. My 2dr doesnt shake full throttle maxing out thr speedo lol

How about taking it to a front end shop and having them do an alignment.

I forgot to mention that I also put two brand new hubs on and new front axles as well. I have 4 different sets of tires and rims on it. I have also have taken it to an alignment and still the same issue. Tires have also been balanced.

i would say 4 different sets of tires and rims can be a contributor.

^^^ this

If I'm reading that right 4 different tires and rims can really cause some issues, ESP if your running different sizes and If you are running different sizes you can damage your 4wd

Sorry about the mis understanging but its four different sets of tires and wheels. I'm not mixing tires and rims.

Mine doesn't shake at 55 MPH either.

OP: Have you looked at other things that aren't suspension related that would cause shaking, ujoints, gears/bearings inside the housing, rotors, stuck brake caliper, pads, drums ... anything that turns, including transmission and engine internals ...

 

[SunlitComet]

if it is shaking it would likely be anything downstream of tranny output shaft. or even a motor or tranny mount. anything forward of the tranny output shaft would be more of a vibration. and if you do rebalance pay attention to the amount of weight each assembly takes it will give you an immediate clue if you have a screwed up tire.

 

[retorq]

Hahaha seriously?! What's the difference between a vibration and a shake to you?? If his ujoints were bad enough or he stripped some teeth off his pinion gear and it was way out of balance, he would have "shake", not a "vibration".

 

[SunlitComet]

read it again and in the way of power flow. and yes i did change two letters. for SPELLING purposes.

 

[retorq]

Still interested in hearing the technical differences between a vibration and a shake as explained by you ... If you can actually do that, that is.

 

[SunlitComet]

google or wiki it. i am not going to sit here and type out mechanical principles. i am kinda getting tired of having to explain everything sometimes. i have done enough of that already by now that i should not have to explain myself over and over and for a simple repair job it is too much to have to get involved in.

 

[retorq]

Shake = vibration, plain and simple.

OP: mine does the same thing 65+ mph. and i have replaced the same items. next on my list to check/replace are control arm bushing, engine mounts, trans mount, entire truck......
did you ever figure out what the issue was?

I have a 2dr 2wd. Since I have bought it using stock wheels, 15" centerlines to the Ultra 20" 5 spokes I have had this same problem.

I had the drive axle rebalanced with new u-joints.

I still have the shake, shimmy or vibration you are talking about. I have lived with this since I purchased this in 2005.

Drums have been replaced, rotors have been replace. I am down to rear axles.

On mine you can lift the rear wheels off the ground, put truck in gear and its smooth up to about 60-70 mph and then it will go into a real bad shake. I have had it at 5 shops here in Orlando and they have no clue. I even had them replace the tires , move tires from wheels to the other corners etc and still no issue.

We must have an issue with something in our Tahoes.

 

[retorq]

Which is it, shake or vibration?? They are different according to what's his face lol.

I've had mine up to 100 with no shake, it's not an issue with our Tahoes, just the ones that aren't treated right.

You may have a pinion bearing or axle bearing issue. Could be a couple things in the transmission as well ... does the vibration/shake go away if you get it up to speed and shift it into neutral?

 

[Loki]

not sure ill have to test it out tomorrow and get back to you on that one.
