Default What's the best way to align the engine cradle?

Got my cradle back from Martin. Is there anything special to aligning it? Want to make sure I have it centered so I don't have alignment issues.

Thanks,

Jason

If you're talking about the front subframe, it basically self-aligns. There are two holes that are a relatively close fit to the studs on the unibody frame, the rest are pretty loose. Probably a good idea to take some diagonal measurements to make sure nothing's really out of whack, but if you can fit the subframe to the studs and bolt it in with all the bolts/nuts tight, you've done about all you can do.

It felt pretty tight just trying to get it reinstalled, so I figured there was not much play, just wanted to be sure.

Thanks,

Jason

That might not even be the same sub-frame that you sent him. I know that the oil pan & rear hubs that were returned to me were not the ones that I sent.

Jason,
I measure the sub frame before modifying.
Sometimes they change shape while welding even in the jig.
I use a hydraulic ram to bring it back to as close to spot on as I can.+-.050"
It is your sub frame in case you were wondering.
I gather your alignment issues are the two back bolts.
Not to worry. Pry bar works great.
