Here come the rear corners..

Hi all,

Well, I have a pair of steel rear corners coming next week and I've been taking a good look at the back end of my 93 YJ in preparation for the drilling and clamping to come, and I've been thinking, "Damn.. what did I get myself into this time?"

Any advice for a first-timer? I figure if all goes well I'll put some rockers on the rig next and then go from there, but this is my jeep's first modification.. should I expect any surprises?

Thanks everyone..

It is pretty straight forward just clamp them on drill a hole and bolt them up tight. I did put some silicone behind them to seal them and then ran a bead around the edges. I have hardly hit the corners since I installed them, but it is nice to know they are there. Jim F.

I have often wondered what is best as far as the silicone... seal it up and trap in moisture or none at all so it drains and dries.

Assuming the rear corners are metal..... There's nothing good to be had from not grounding metals to metals. Molding is plastic, thus nonconductive, and will be fine not being electrically grounded to the vehicle ground. With metals, isolating them from a ground can cause cathodic action and actually invite corrosion. Especially if there is ferrous and non ferrous metals involved such as aluminum diamond plate and steel. Bolting with zinc chromate paste (anti seize) as the medium is highly recommended.

Cherrs!

They ain't no zinc chromate in anti-seize...

Sorry, I beg to differ. I used it extensively in training folks on anti corrosion in the US Navy where salt water was always prevalent. I agree there are other compounds but I'm partial to Zinc since it was (and still is) the military's (Milspec Mil-T-22361) choice of compound of my time. Military NSN: 8030-00-292-1102 Anti Seize compound is what I use and is still a common product today in the Navy to protect steel and aluminum components bolted on steel ships exposed to salt water. I'm not willing to try something new since I have had no corrosion apparent using this compound ever in the past 25 years. For a non military resource ref:

The main point though for which we both agree was to not isolate the two metals electronically for fear of electrolysis or cathodic action which leads to corrosion.

For anyone out there.... ever wonder why your cast aluminum fog lights corrode so quickly? It's the lack of good grounding and proper medium compounds to protect against it.

Cheers!

PS. It works great on battery terminals too!
