It's becoming a regular sight seeing front shocker dust boots being split on 3rd Generation CR-V's. I've taken some pictures on the general process of how they are replaced and illustrating just how bad those boots can get.
- Difficulty Level:
This is a split boot
The boots then separate into rings
And these rings have and do get jammed in between the piston and body causing a failure of the shocker. Which is very dangerous!!!!
I have seen a few CR-V's with blown shockers. They drove like a nodding Churchill dog! No damping at all, when you brake the car just keeps bouncing. The oil gets sprayed over the brakes and tyres as another consequence. All in all not very good realy.
So here is guide on what's involved in replacing them.
Remover the top mount bolt covers
Slacken the 14mm nuts
Remove the front wheels and undo the 2 main shocker nuts leaving the bolts through the shocker for now. Remover the speed sensor wires, drop links and brake flexi hoses. Support the shockers. I use axel stands under the discs
Now you can remove the upper 14mm nuts and 2 main shocker to hub bolts releasing the shocker from the car. The axel stand is there to keep the driveshaft from extending out of its socket. There is nothing supporting it with the shocker out.
This is where you need spring compressors. Note there is a marking to line back up when re-building. It should line up where the hub sits in the shocker
The spring clamped down and top mount removed
grease always helps everything to sit properly and is good practice.
Hers a new boot greased ready for fitting in place
And for the blue Peter moment. Here's one I made earlier
with a nice shiny new dust boot.
It's not the nicest of jobs. And if you have never had a shocker apart I would not recommend this as a DIY. Some jobs need to be done properly by a mechanic and this is one of them.
Hopefully this will give you an insight into what is wrong if you are told the boots are split and what is involved in replacing them. Its important to realise how important there roll is and that if any loose rubber does get trapped in the piston its a lot more costly for a new shocker.
