Drive shaft oil seals?

Is it true that the original seals fitted by the manufacturer are different to those used to replacement seals?





My previous garage told me he changed them. My new garage say he didn't because the originals are still in and they are different to replacements.Drive shaft oil seals?
Yes the after market one are a little different but the sizes are the same so you wont leak oil,the original ones will have makings one them and if they were replaced then they should not have to be replaced again so soon.Drive shaft oil seals?
The main way to tell the difference is the part number stamped on the seal and sometimes the color. If you can get the number off the seal you can call a parts store like advance and they can cross reference the part number and tell you if its original or not. Most mechanic will not get replacement parts from the dealer, so if it is the original part number then you know he didn't change it.
well its possible to buy parts from dealer


which wil be originals manufacturers parts


was they leaking was they not leaking then he replace them cant say he didnt can say they look old or not and can guess





originals manufacturers parts


and after market parts many time made by same company just one has pass a test from company to be good car companie dont make many of their own parts they buy them from companies who make them for them what makes them originals is they come from factory which you can buy from dealership or sometimes a parts store sorry cant say they not originals part or not by numbers can look at them and see if they bad or old
most aftermarket sources use a seal with is identical to oem. if the seals are dried they will leak eventually.
most of parts that garage install are not original so its thrue they are not the same as the original equipment
well unless they are seals from the manufacturer then they will have some small variances. I'd say you get another shop to look at it before making a decision.
