another noob question....

[dirtynewsubie]

what could cause the 5spd manual trans to feel heavy when you shift and put it neutral and cause the whole car to shake like crazy. It stops for a short time when you slow down but then starts right back up.

[WRXCMM]

it might not be the tranny, it sounds to me like the rear diff...i don't know...

have you checked oil in both lately?
have they been serviced?

[dirtynewsubie]

not sure if it has ever been changed and i havent changed it in the 10k i put on it. The rear dif would cause the shifter to feel like the trany fluid was frozen? Both symptoms happen at the same time

[GearheadV8]

What is the weather like there cause that can have a factor on it. After you drive around for awhile does is it seem to stop?

[dirtynewsubie]

just a normal ohio winter, right now its about 30 degrees. It only starts after driving for a long time

[TOI]

im not a subaru expert, but normally when a trans. is cold its heavy before being driven on. do you know what weight oil your using?

[UP2MTNS]

got snow/mud/dirt in your rims? cause if you put it in neutral, and the car is still shaking, its not your tranny.

[dirtynewsubie]

everything is warmed up when it starts shaking, it usually starts after driving in 5th for 10-15 min at freeway speed after driving for a long time. it dosent do it in first or second, it starts at higher speeds. Where are the fluid checks for the diff and tranny?

[WRXCMM]

if your car is mt then the tranny fluid check stick will be accesible though the passanger side below the intake box (assuming you have n/a) it should be abvious it will stare right at you when you see it it's orange in color.

as for the diff, you would have to remove the top nut (i really don't know what to use i haven't done it) the fluid should be at the lower part of the hole (assuming your car is in a level surface).

clear your wheels of snow and ice. They tend to get unbalanced at this time of year in the snow ridden areas of the country.

what bolt are you talking about? one of the big plugs on the back of the diff cover? and i cant find a dipstick on my car anywhere under the airbox, is it different on an 03 because my car seems to have some repairs with parts from 03's and there different than 02

[GearheadV8]

I would say check the oil wt for sure. Cause I know at different altutudes it can effect different things so it might be affecting the oil in the trans in a negative way witch could be causing the problems with shaking. It is a pretty far fetched possibility but it is worth checking lol

[dirtynewsubie]

this has me and my brother who went to wyotech stumped. i think ill start by checking all the fluids if i ever figure out how and then replacing them

[Dubld]

could this be cv joint problems?

[dirtynewsubie]

i dont think its the cv's cause they never started clicking

[dirtynewsubie]

SOLVED! Low fluids+my car=:cry: full fluids=:headbang::guitarist::machinegunleft:(aka AWESOMENESS!!!) Thanks to everyone for all the help!

[WRXCMM]

please make sure to drain everything out of the tranny if it had been low for a while, then fill it back up.

[dirtynewsubie]

could this be cv joint problems?
Could this be the C.V's? I changed all the gear oils and while under the car i noticed that the cv boot on the driver side close to the tranny was throwing grease ant the passenger side by the wheel. Could this be from bad cv's? I really hope its not the next step because i cant afford to rebuild my tranny

[dirtynewsubie]

bump! I need help!

[Bubba02sti]

if thier is grease everywhere then it is most likely a cv... just go get the whole half shaft its cheaper and easier... I think they are only about 60 bucks... I would do both sides at the same time though casue like anything else if the one side is done the other is most likely to go soon as well... here is an easy way to check though... jack the car up... spray the piss out of the inner boot or where ever you are seeing the grease get splatterd... lower the car... take it to a parking lot and do simple parking lot manuvers... slow left right turns on throttle 1st and 2nd gear driving... don't go fast though... if you hear a humming noise a "bad strut" noise then its most likely your inner CV boot... if the inner boot is gone its not going to make the traditional clicking noise of the outer boot going out... go home jack it up off of all for wheels see if there is anymore grease throwen around... see if you can have a buddy manualy turn the wheels to see if you can find a tear in the boot...

[dirtynewsubie]

I have checked the rear C.V's and there is no sign of grease annywhere near them. I was going to replace them one at a time because i dont have the money to replace them both at the same time. I really think its the C.V's because the front C.V's are bad on my moms 99 obs and it does the same thing but the vibration is not as violent. Has anyone expeierienced(or however you spell it) anything like this?

[snaggleto0th]

And you went to WyoTech? please tell me collision? JK dood no hard feelings, I still get stumped with **** and I went to WyoTech as well! As long as you didnt say UTI your good in my book man!

As UP2MTNs said check your tires, make sure they are at the correct pressures. Check your tranny/engine mounts the shifting of weight can cause some issues and vibrations. If a CV boot is throwing grease its most likely going to go out, so replace the shaft its cheaper, and easier to replace the shaft than the boot(i know cause I had my front left go out and the boot was $15 cheaper than the whole shaft). And if the front CV's were bad they make more of a clicking and clunking nouse while turning and thats about as much you can get from a bad cv, unless they snap into pieces and your car doesnt move(had a car come into my shop like that, car starts put it in gear and watch the speedo do 100mph in 1 second).

if your tranny and rear end were bad, they wouldnt make a vibration, they will make a noise such as clunking, gear whine, grinding, and such forth. As I said check your engine/tranny mounts (especially the dog bone one under your intercooler).

[dirtynewsubie]

no i didnt go to wyotech my brother did, impretty much self taught, i didnt get to even though i wanted to:FU:. I am replacing the whole axel on both sides and im pretty sure all the mounts are good but ill check them when im replacing the shafts. As far as mud in my wheels there is only a small amount but thats impossible to prevent because i live in the sticks

my boy Jason (DI member jlcjr42) bought a used 07' STI that had a terible shake when he got up to about 50. bent rim + bad balence + bad allignment = the problem. check that out. im not sure if you fixed the problem yet. i didnt have time to read all posts. also check your wheel bearings. they might cause a vibration. dose it come and go depending on which way your turning?

It has nothing to do with turning and it onlt starts when you drive 55-60 in fith without shifting for about 10-15 min after its warmed up. i checked all the engine/tranny mounts, all good. the rear axel c.v's are good. the center support bearing is good the only thing that is bad is the front cv's

[snaggleto0th]

When you replace those let us know. It would be something new in my book if they were causing a vibration, only way i see them causing that is from when they are about ready to explode and they are just shaking around so much from the speeds of 55-65mph. I would check into getting your wheels re-balanced I have seen that cause an issue with my personal vehicles and with the front tires being low. Keep us posted if you get new symptoms or figure it out.
