Half-axle (CV joint) replacement in a 1997 Subaru Outback

Filed under: Uncategorized — Tags: , , , , , , , — admin @ 5:02 am

Our trusty 1997 Subaru Outback AKA “The Nimbus” recently began to exhibit the standard symptoms of CV joint failure: popping/clicking noises when turning, and grease escape. When I first reached under to check it late at night, I got a hand full of black grease from the exposed innards of the CV joint. Closer inspection revealed that the rubber CV boot on the driver’s side was actually torn apart.

My Subaru Outback Head Gasket Repair


Don't try this at home.

This could be your Subaru (parts).

I have a 1997 Subaru Outback with about 280,000km on it. It began showing the head gasket failure symptoms so typical of the Subaru boxer 2.5L engine of this series of cars: foaming/bubbling in the coolant (the reservoir actually looked like a boiling kettle when the engine was running), brief random apparent spikes of the temperature gauge, and coolant loss. Much has been written elsewhere about this issue, and there are a few references about the problem and some repair examples at the end of this blog. Known model years affected by this problem are at least 1996-2002, so be aware of it if you are looking at a used Subaru of that age. I decided to do the repair myself, being very inclined to tinkering, foolish enough to attempt it, and also being unwilling to spend about $2500+ for a shop mechanic to do the job.

Edit Oct. 2011: A few people have asked me about the “head gasket sealer in a can” products. There are a few on the market. I actually had tried one of these, Bar’s Leaks, before I did the real repair, with no success. What I’ve seen in other reports is that they simply don’t work on “internal” head gasket leaks such as what this series of Outbacks gets. Furthermore, given how severe the gasket damage tends to be, I don’t have much confidence in them. The gasket replacement job looks to be the only option, if you want to keep the engine. The good news, though, is that you don’t need to remove the engine from the car to do this repair.

Here are some details of the head gasket repair that I did, in case it helps anyone else trying to do the same thing. Note that this is a big job, (more…)
