It seems that your axle shafts and such were just changed and the surfaces were never looked at that ate up those seals in the first place.. the brakes are adjusted too tight and this is also causing heat to buld up in the wheels..this can also burn out the seals and cause failure..gotta take it all apart again and check the bearing seal surfaces for any burrs or reasons for these seals to get cut up.. also when reinstalling these put some gear oil on the seal surfaces so they arent dry-ran on the shafts..this will destroy them also.. clean off the oil on the brake surfaces wit carb cleaner so it will evaporate quickly then reassemble..wheels shouild spin freely with little drag on them while turning by hand..

SOURCE: Rear Axle Leak

if it is the seal, you will have to remove the caliper and rotor, remove the differential cover and remove the bolt and pin inside the diff carrier housing. push in the axle and remove the axle clip and pull out the axle use a seal puller or prybar to remove seal reverse the steps to assemble

SOURCE: Left rear axle seal is leaking differental oil.

ok then here is the procedure  1 take off the axle nut
2 on the lower control arm you will find a large nut and bolt i belive the nut is a 21mm and the bolt side is an 18mm. this bolt is the one at the knuckle near the brakes. remove it
3 you will need to pull the knuckle out of the way or a helper to pull the knuckle out of the way so you can slip the axle out of the knuckle.( its a tight fit but there is room to slip it out.)
4 use a pry bar to pop the axle free of the diff. hosing its held in by a spring clip make sure the clip comes out with the axle if it gets stuck inside you will have to fish it out.
5 use a pry bar or screwdriver to pry seal out of housing then use a flat object that contacts the entire rim of the new seal so it can evenly be installed with out getting smashed and tap it in with a hammer. ( a good trick here is to use some grease and pack it into the new seal where the spring is this will prevent the spring from being shocked out of the seal during instalation . the spring keeps tension on the rubber in the seal so it stays tight to the shaft it is sealing.)
6 then revers the above steps. also make sure you are using the right gear lube it will most likely be 75w-140 but make sure you check your owners manual will tell you if it doesnt say on the diff cover. you can cause a lot of damage if you put in the wrong thing. and make sure  you feel the axle spring clip snap into place.
as a note there are two types of axle seals that are used on these so if the new seal looks different than the old seal then the folliowing will be important to you.the seals on these have been redesigned so if you axle has what looks like a cup or dust cover pressed onto the shaft where it goes into the diff the new style does not use this and it will prevent the axle form going in all the way so the spring clip will not lock in and you will have a leak. so you will have to remove it and install the axle without it.

SOURCE: My 03 Maxima (3.5l 255 hp) started burning oil at

All cars will lose a certain amount of oil because you cannot seal an engine completely nor do you want to. Oil is lost at the valves, the piston rights and some oil is spread into the intake as blow-by occurs. This is normal to loss a quart of oil within 4,000 miles. However you are using a synthetic oil which is a man made oil and has different charactaristic than regular oil. You will loss more oil using oils like Mobil 1, but that is normal as well.

SOURCE: Smell of burning rubber rear offside wheel area

Hi there! Check out this link.
http://www.automotivehelper.com/topic175126.htm
this link will take you to a forum full of people with CRV's who are having the exact same problem. It seems to be with almost every year of the CRV as well. Unfortunately Honda has no explanation or solution for this problem. I have a 2009 CRV and have not had this smell, but I have been having a ton of other problems with it. I have been incredibly dissapointed with this car, and will never get another Honda. I hope you have better luck than I, and be careful with it cause I think there are some serious problems with these CRV's. Good Luck!

Why is my 2007 300c burning oil


You do not say how much oil the car is burning. One quart every 1000 miles is ok. Cars with 75000 miles or higher are likely to burn more oil than cars with less mileage. Try using high mileage motor oil. If excessive smoke is coming out of your exhaust pipe, you are either leaking oil through the piston oil rings or valve seals. Then you will need an expensive repair.

Blue smoke


Blue smoke (how many miles on engine, 50k or 500K???????
to some this means, burning oil, others steam
it that blue smoke lingers a long time that is oil burning
and smells just like oil burning.
and means 2 things,
1: engine burns oil.
2: if car had autotmatic trans the vacuum modulator love fail
and suck ATF fluid to the intake plenum and burn it, and bingo burning oil like mad.
3: PCV valve packed solid,and forces engine to leak oil or burn oil. or both. this is a 50k miles service point, skipping this?
4: gas in the oil making it thin and not sneaks past valve stems.
does oil change cure this.>?

now engines.
worn out engines smoke. (burn oil)
as do bad valve guides and seals.
and bad piston rings.
100 years same story, and miles matter. History on engine too.
matters.

The engine uses alot of oil. The head gasket and valve seats were replaced. And the problem stills exist.it uses a half to a full quart within 100 miles


Well if it's not leaking it, it must be burning it. Do you notice blue smoke out your exhaust? You say that the head gasket and valve seats were done. How about the valve guides? Oil can go past worn valve guides and valve seals. The only other place that oil can be getting by is past the piston rings.

Van used 2.5 quarts of oil in 1200miles no sign of oil burning or blue smoke at tail pipe. oil light comes on frequently 2004 dodge caravan


If there is no sign of oil consumption, then you have a leak some where. Un-noticed leaks are usually found at the rear main seal and leak as you are driving. If you crawl under the vehicle and closely inspect the area where the engine block meets the transmission you may find evidence of an oil leak.

Its burning oil I put a quart in every 100 miles or so??


Sounds like you have a problem with your valve guide seals leaking oil into the piston chamber...
When was the last time you changed the oil? Does the vehicle actually smoke?

Oil Leaks I have an 2003 Mits. Galant GTZ...with117K miles. My question is, i've noticed oil spots on the ground under the car, a burning smell when i've driven along with smoke. In addition to a squealing...


the seal will gradually start leaking more as time goes by and needs to be replaced, but in the mean time if u keep the oil full and it does not go below low line on dipstick you can drive with no engine damage. sometimes adding oil leak additive to oil will help , using a slightly heavier oil during warm weather will often help reduce oil loss and give you more time to get enough money to replace seal. If engine gets too low on oil it will cause major engine damage.
