Subframe Removal Advice
 
Long story here...but in working on a suspension refresh I may be at the point (thanks to corrosion and snapped bolts) where it makes sense to just replace the front h subframe. Anyone removed this item before? I only ask because it looks as straightforward as unbolting it from the car and control arms and lowering it, but I wondered if anyone else had experience with what else might come with it when lowered? Anything to be aware of? Thanks in advance.

Straightforward. I believe you need to unbolt the rack also

Thanks for that. Got the old one down. Ended up supporting the fuel tank with a jack stand as I wasnt sure how far it would drop. All came out well. Now I'm waiting on the new frame and then will have to repair some shredded threads for the control arms to the body. A lot more than I bargained for, but it will be cool to say i did it when it's all done.

You will need the help of a body builder to torque the bolts on the subframe :p

Oh boy. Haven't looked for torque values yet.

I think the highest torque is like 118. no big deal.

Sorry to jump on an old thread but what do I need to disconnect to drop the front subframe, I need access to replace rusted brake lines.
I have loosened the x6 subframe bolts but am guessing I need to separate the steering shaft from rack at least before dropping, do I need to undo strut top mounts?
Any help appreciated
Thanks Craig

Hello Craig,

No, you don't need to separate the steering shaft from the rack, but you need to remove the bolts that secure the rack to the subframe, if I remember correctly I held the rack to something above it (cannot remember what..) with a couple of zip ties to keep it ouyt of the way. Good luck!

Thatís great Gilles thanks for the advice much appreciated I assume you mean the x2 bolts or so that go through bottom of subframe?
Will give it a go tomorrow, I have managed to remove the old brake pipes which were in a real mess, I lost brakes when one of the steel pipes ruptured not the best experience.

Hello Craig,
Yes, these bolts attach the steering rack to the subframe and you will be able to hang the steering rack (w/zip ties) without disconnecting anything from the steering system while you lower the subframe.
