TD90_nw Posted March 5 Share Posted March 5 (edited) Greetings everyone, I'm in a bit of a conundrum after doing some work on ol reliable. Vehicle: 91 Subaru Loyale Here's the breakdown: we pulled the motor for a clutch replacement and while we were at it, we also replaced the front axles, outer tie rods, distributor cap/rotor, spark plugs/wires, and both drive belts. It was quite the undertaking, but we managed to get everything back together – or so we thought. As we were wrapping up the job, I noticed there's one bolt left over, and it's been bugging me ever since. We meticulously accounted for every bolt and nut during disassembly and made sure to keep track of everything. I used plastic bags and labeled with sharpie what bolts went to. However, despite our efforts, this one bolt seems to have slipped through the cracks. I've gone over the areas we worked on multiple times, inspected the engine bay, and crawled under the car, but no luck. It's like playing automotive detective, trying to figure out where this bolt belongs. Given the extensive nature of the work we did, I'm a bit concerned that this bolt might be crucial to the operation or integrity of some component. It's not the kind of thing I want to leave to chance. So, fellow enthusiasts and seasoned mechanics, I'm reaching out to tap into your collective wisdom. Have you ever encountered a similar situation after performing major repairs or replacements? How did you go about tracking down the origin of leftover bolts? I'm open to any suggestions or insights you might have. It's a head-scratcher for sure, and any help in solving this mystery would be greatly appreciated. I'll throw in a pic of the bolt. I'm hoping someone with much more experience than myself can chime in! The bolt is 14mm if that helps at all. Thanks in advance for your assistance! https://tinypic.host/image/IMG-2867.D2uiIR Edited March 5 by TD90_nw Quote Link to comment Share on other sites More sharing options...

And it’s too short for a suspension arm bolt. I’ve had this many times without issue. Keep the left over bits aside in a labelled container incase you find a missing bolt. While they’re off the vehicle consider the effort as weight reduction. Cheers Bennie Edited March 5 by el_freddo 1 Quote Link to comment Share on other sites More sharing options...

moosens Posted March 6 Share Posted March 6 r a clutch replacement - engine to bellhousing ? and while we were at it, we also replaced the front axles, - only at the knuckle if you loosened to assist axle r&r outer tie rods,- not seeing a 14mm bolt there distributor cap/rotor, spark plugs/wires, - have all the wire supports if any, back in place? and both drive belts. - not timing belts right? Anything else you may have moved aside to assist access? 14mm head is a bit sturdy for something like an overflow bottle mount etc . Good mystery.

Can't recall at the moment if stock pivot bolt is 10 mm or 12 mm shank diameter. Strut knuckle bolt maybe? Edited March 6 by czny 1 Quote Link to comment Share on other sites More sharing options...
subaru1988 Posted March 6 Share Posted March 6 The Factory Service Manuals that are floating out there have bolt sizes and torque measurements in them. What I would do is match the bolt to the bolt/torque sizes in the guide. You could then use the exploded diagrams in the FSM as a map to show you where a bolt that size could have come off on the areas you actually worked on. 1 Quote Link to comment Share on other sites More sharing options...

I’d double check that you do in fact have the ball joint retainer bolt in place on either side and done up appropriately tight. You don’t want one of those ball joints dropping out and letting your hub take its own unplanned trip! My other thought was also the engine pitch stopper rod, I wonder if this was replaced with another bolt from somewhere else… Being that this was a “we” job - as in we did this and we did that… old mate isn’t stitching you up by placing this Subaru looking bolt in the mix of all your other nuts and bolts? That’s something a good mate might do as a prank! Cheers Bennie Quote Link to comment Share on other sites More sharing options...

Did the OP replace a ball joint while at it? We don't know, yet. BUT, sometimes there's a new spare bolt with nut included in ball joint kits.

Good news is the car still is intact and everything seems to be functioning properly. Cheers everyone thanks for the help ill update if anything happens.

idosubaru Posted March 8 Share Posted March 8 It looks like a bolt and nut to keep with a chain for lifting engines, etc. 14mm old gen bolts: suspension: ball joint, cross member. Most are 12 but some engine accessory bracket hold down bolts - like A/C bracket, P/S, Alt are 14mm. bellhousing and head bolts but this isn't one of them. 1 Quote Link to comment Share on other sites More sharing options...
