Many thanks - saved me a bunch got a new mast/rack for $12 on ebay.

My rack was snapped with one "loop" remaining in the holder.

Would have taken me an hour but I had one problem - when feeding in the new rack, I hit a ledge or something and couldn't get it past. I took the motor unit out again and checked the "pipe" wasn't blocked. It wasn't. The only way I could thread the rack was to shave it to a point with a utility knife (just a quarter inch at the end). After wiggling, went in a treat.

Thanks again. Here are a couple of pix that might help others...

HI Gruss et al, 

I realize this is a very old post, and thanks for the pics! However, it's not necessary to remove that heavy spare tire cover. Please see the "how-to" pic in my thread over at https://www.clublexus.com/forums/rx-1st-gen-1999-2003/641262-re-rx300-antenna-and-or-motor-replace-repair-complete-instructions.html

Again thanks to truebr1t for this detailed motor/mast maintenance tutorial. Very helpful.

Regards . . .

P.S. Moderator: Can you please clean this post up for me by removing what appears to be a double set of quoted pictures? I don't see any way I can do this myself. Thanks for your help.

Has anyone had issues with a weak signal after installation? I managed to install everything just fine, but afterward, both the AM and FM signal are no better than before, as if it weren't installed at all! I checked that the signal cable was secure - what else could it be?

Thanks-

I realize this is a very, very old post, and I'm not 100% sure about this solving your problem, but . . . When you remove the motor mount, antenna wire and white motor control wire plug, and pull out the whole mast assembly to work on, you notice a short black grounding wire runs from the upper area of the mount (isolated in rubber bushings). This black wire attaches to one of two bottom screws that holds the motor onto the mount. This is how the mast gets grounded to the vehicle frame. When the mount is bolted into place, that screw is positioned at the lowest part of the mount (ie. closest to the pavement), in such a way that any water that runs down the outside of the mast or mount (or overflows out of the drain tube), will pour over that screw, and the wire hoop, thus corroding the galvanized wire mount area, the wire mount hoop, and/or the copper wire inside that black plastic wire. When I saw that nasty corrosion, I used a metal brush to clean up the wire hoop (ie. down to brass) and then relocated the wire hoop to the other bottom screw (with a little lock washer under the screw head). This alternate screw location is not the lowest part of the mount and won't get any water on it.
