Hello

I had to do clutch replacement for my MY '01 S and off course needed to lower the subframe. Front bolts (nr. 10 on picture) were badly seized and both snapped. I had to drill and re tap.


I ordered 2 new bolts. Part number: 90162-S2A-000

Old bolt probably look'd like this:


But new bolt looks like this:

Part number is correct. On new bolt thread is too short. It goes thru the thread in chassis before it tightens against the subframe.

 

Looks like the part diagram is incorrect, you should have ordered 90161-S2A-000

 

You were right. Got the right bolts. Thanks again

 

In order to drill and retap the thread, did you drop the whole subframe, or were you able to go through the bolt hole in the subframe. I'm stuck in a similar situation right now.

 

How did you get on with this?
It happened to me and I am planning to get working on it in a few weeks. Any advice welcome

 

Did you actually break them? That is pretty tough to do but possible. If not broken, then the process is to run them back and forth with an impact, allow the bolt to cool a bit after every few cycles. The bolts stick up into a cavity and the ends get corroded, then when you loosen you drag that corrosion into the threads. Typically by running them out until they start binding, go a bit further, then back in and repeat, they will come out. Once you get enough of the bolt showing you can start spraying the threads with penetrating oil to help work that up into the threads. A friend and I have gotten some pretty stuck ones out this way on his.

 

I followed Billman's preventive advice on this very thing with my 2009 last year. Ran out each one, one at a time, cleaned and applied anti sieze, reinserted and torqued to spec. Then repeated for the others. Only one was a little goofy to get properly inserted but over all it was a pretty smooth operation. Used my M18 torque gun to break free and then went by hand to feel any resistance. No real corrosion. Must be the west coast dry climate.

Wanted to head off problems like the above off at the pass down the road.

 

What happened? A broken bolt?

 

Yup broken bolt on both side! Happened during a clutch change. I was using a breaker bar and heat but caused them to both snap. Hind sight is 20/20 and in future will be going for the slow and steady approach.
When you drilled and tapped did you just tap or did you use Helicoils?
Did you need to take the subframe out completely to access?
Trying to get prepared before starting this job. The car is at my parents so want to get all the tools (and mental prep) in before heading up there.

Saw your post @B serious and this it might be my best option. Any tips for this?
