this sucks man i did the same thing that you did and still shakingsame thing with me
you changed the axles and rear mount?this sucks man i did the same thing that you did and still shaking

yea all of that
what else have you changed?yea all of that

my friend said it can be the rotors because its off balanced and not smooth
what about ball joints? wheel bearings, and tie rods? Steering rack and pinion?still shaking as of today ive changed the driver side axle 3 times the passenger axle 2 times and the half shaft once
have these areas been ruled out?

bellow boot (innertie-rod dust cover) in itself being broken will not cause problems. but it appears that the bellow boot is quite wet inside. this wetness is from yoru rack and pinion seal. the rack and pinion seal is what the bellow boot is there for so dirt and debris wotn damage the seal.
you will need a new rack and pinion..but this is NOT causing an issue so honestly i wouldnt worry about it unless you dotn like filling up your power steering resovir. if it is a manual rack then i really wouldnt worry about it at all. will still last quite a long time.
now for the vibration issue at hand.... it WILL NOT be any front end part like mentioned earlier. i will explain in detail since im tired of posters spurting out front end parts.
it will not be bearing... bearings dont vibrate at any speed. a bad bearing will growl or moan and will be noticiable the faster you go. this growl or moan might feel some vibration on the car but will "not" vibrate your wheel back and forth. bad bearings will change pitch when you turn if they are the frotn bearings. bad bearings will not quiet down at any speed a.k.a. stop making noise during a certain speed. they will have a jet like effect where the pitch is stronger and higher..then the next faster speed will make the pitch stronger and higher yet..then the next faster speed.. and so on.
it will NOT be a bad baljoint/tie-rod/inner tie-rod/upper balljoint/or even control arm bushings. sure you could have play in any of them but they will not vibrate down a smooth road. lets say for arguments sake you have an inch looseness in the listed part above. if you drive down the road that inch movement will kick out fully max. you will continue driving with the balljoint maxxed out at that inch.. (newtons law says some stuff about an obeject will continue path until another force is acting upon that same said opbejct) if you were to hit a bump (suspension travel) or accelerat harder..or decel (brakes applied) that you are creating another force to move that balljoint. it will move "once" to the other inch maxx side of the spectrum. it might even have a small ripple effect (vibrate) when you change forces on that balljoint. this right there is where people say "yoru balljoints cause vibrations.." which in fact they really dont!
a bad motor mount is kind of the same way as mentioned above. it will kick maxx side then min side only when force is applied.. i.e. braking, hard accel, shifting or possibly a bump or dip in the road. it will not be a set vibration while cruising and definetly will not go away at a certain speed. these are really checked at idle or throttle snaps at idle.
a bad alignment or alignment out of spec. same rules apply.. alignments will not cause vibrations. they could wear your tires unevenly and then that said tire might be out of balance resulting in a out of balance tire which could cause a vibration but your alignment is the the problem..it would be considered a cause of your problem. alignemnt angles just that.. an angle of your tire to help promote tire wear and handling on your vehicle. if one angle is out the tire will just ride at that angle... it wouldnt vibrate at all.
now for the things that CAN cause a vibrate down the road at a certain given speed.
balancing of your tires... if the wheel shakes then it will be front balance. if your ass shakes or the car shakes then i would look at rear balancing. just because a said shop just balanced your tires doesnt mean they did a correct balancing style or even a good job at balancing. normally 60 mph shake is balance..and it would go away the faster you go... i understand your speed is lower then this .
a bad tire or bent rim.. this too could cause a vibration but generally it will be considered a "low speed wobble" low speed is generally 25-30 range. your speed is also below this i undertsaand.
halfshaft can cause a vibration.. for your speed and such this is where i would look first. its not uncommon to have axle problems that cause a vibration at a specific speed.
last one that can cause a vibration is often overlooked. brakes!. vibration while braking is bent rotors or warped drums. pull your e brake to tell if it is in front or rear.
another brake issue which can cause a vibration while "cruising" is to tight of a drum adjustment. this can cause the shoes to engauge and disengauge (a.k.a. skip effect) while cruising. would get worse the longer you drive it but wouldnt go away at a given speed liek you mentioned.
sorry for the novel but jus wated to clarify some thigns and extend your knowledge about simple mechanics.
i would start balancing, rotate of tires, rear drum brake adjust then halfshaft in that order.
ok so what are you saying? everytime we offer a suggestion and you tell us no and go find something to prove us wrong if your doing that why ask for help. very imformative, yes obviously bad tires and rims/wheels will cause vibration but i dont care what that says, if something is loose (ball joint, tie rods, engine mount,) the front of the car will shake. you have already replaced the axles more than once. its not that so move to the next issue,
are your tires wearing correctly?
are they inflated correctly,
is your front end aligned properly?
do you have bad ball joint, ( are they tightened as well?)
are your tie rod ends in good condition? (also tightend as well)
are your camber arms tight?
are your front shocks seated properly?
even though you can physically see these parts and see if they are tightened or in working condition check again.

i simply just posted that quote i found on another fourm because it has some helpful info you guys might like to read, it makes sense but at the same thing you never know.ok so what are you saying? everytime we offer a suggestion and you tell us no and go find something to prove us wrong if your doing that why ask for help. very imformative, yes obviously bad tires and rims/wheels will cause vibration but i dont care what that says, if something is loose (ball joint, tie rods, engine mount,) the front of the car will shake. you have already replaced the axles more than once. its not that so move to the next issue,

my tires are wearing out slightly on the inside but its barely noticable nothing to crazy.
30psi on all four tires
it hasnt been aligned
ball joints are good(yes there tightened)
my driver side tierod has a tiny bit of play
yes there tight
seated properly?
im not doubting him at all im just saying process of elimination. just cause it "LOOKS" ok doesnt mean it is lol

check for air bubbles?
(sorry if its been said, but i couldnt be assed to look through)
worked for me.

With the front wheels removed?still shaking....
ALIGN IT! <<<<< that's the first thing you need to do after working on suspension/axles.i simply just posted that quote i found on another fourm because it has some helpful info you guys might like to read, it makes sense but at the same thing you never know.

inspect the ball joints with everything disassembled . sure the nut could be tight, but the inside of them could be bad.
correct the tiny bit of play in your tie rods.
did you inspect the steering rack and pinion system?
