We’ll shock horror my RAV4 has failed it’s MOT
never had a failure for years.
It’s failed for one of the rear shock absorbers but the warranty will pay for the repairs.
Worse still is they are not confident that they can get one for tomorrow.
So it looks like I’m in the AYGO courtesy car for the weekend with £169 deposit and £169 a month plastered down the side.

Yup, my 4.3 failed for the same reason and also replaced under extended warranty.

I have a suspicion that all these traffic calming measures ( road humps ) are paid for by the shock absorber manufacturers. I replaced both of mine a couple of years ago as there was evidence of a weep on the nearside one. I seem to remember SCHM did a “how to….” which proved very useful, that and some short ratchet spanners for the bottom bolts! |

I don't know about the 4.3 but I changed the rear on the 4.2 before the CT (French mot) and did them in no time, but i did get a local mechanic to do the front as I didn't have spring compressers but he didn't charge me very much (I supplied the parts) |

Maybe my mind playing tricks, but a comment made to me (it may have been from Ancs, apologies if not) was that with the angle they are installed at, they are possibly subject to slightly different forces, compared with a more "traditional" vertical installation and perhaps that leads to a shorter life.
Yeah, the setup should be arranged such that any force is directed along the "top to bottom" axis of the absorber, but maybe other small force components creep in.....

There is a logic to that...the sideways force would put more wear on the seal and chrome shaft 👍🏻👍🏻 |

Correct shcm, shock absorbers are not happy working on their side which wears the piston and seal as Bob says but every time they hit a bump they are subject to a severe lateral shock that wants to snap them in the middle. There’s no real way of avoiding it in the Toyota set up and the strain is slightly reduced by using very short ones but they will always be a niggle while mounted in that way. Mind you, the dealers know it and they will condemn one that even hints at a weep when viewed from a hundred paces. They also seem to be quite happy breaking the “must be fitted as pairs” rule. |

It would also account for the front units ( nearly vertical ) seeming to last a lot longer that the rears. Well in my experience they seem to! |

Have to say that my dealer/MOT station reported 'light misting' on shocks for several consecutive years before replacement was deemed necessary.

When I bought my previous RAV4, a 59 plate, the dealer replaced both shockers even though only one was weeping. It wasn’t a Toyota dealer, I never had a problem with them after that, in fact other than routine servicing I never replaced anything not even a bulb.
Maybe towing doesn’t help.

Touch of double standards..... under Toyota warranty fit individually, when the customer is paying only fit as a pair 🧐 |
