I would just like to haul a small u-haul trailer.Or something equivalent.And I thank you all for being so helpfull.

BTW last place,I think you are right about the 10mm bolts,that makes more sense that they would be a metric bolt.But isn`t that what the -13 is? (metric)

 

Okay guy`s,I finally got the correct information from e-trailer online.For any one who wants to know,the bolts are: 1) 10mm x 40mm hex bolt
2) 10mm lock washer
3) 3/8 flat washer

Again,I would like to thank you all for your help.

Some people skip safety chain for small trailers, though I recommend it for anything in tow.

You'll find the hitch very useful. Besides towing trailers, we also use it to haul mountain bikes. We also have a hitch-mounted luggage rack for hauling stuff that we don't want to put inside the RX (Christmas tree, cooler with fish inside, gasoline, propane, camping trash, etc.)

 

Yeah,thats a good idea!

how to change front marker lightbulb for 1999 rx 300 ?https://www.clublexus.com/forums/images/smilies/pat.gif

 

what will you be towing> sounds like you almost have the hitch situation lined out. i just want to add that you need to make sure your rear diff fluid is fresh and preferably synthetic. also your trans fluid should be fresh before you start towing or at least recently changed. if you tow regularly, keep an eye on your trans fluid. if it starts to smell burned or turn black it's overheating. towing creates a lot of extra heat in the diffs and trans. heat literally kills diff and trans fluid. don't tow in OD up hills if it's a load you can feel pretty well behind you.

 

Thanx 19psi for your extra information.Yes my friend,all of the above has been done,Re:the synthetic in diff,and transfer etc.I will probably hardly ever tow anything,But I want to have it set up in case I need a u-haul,or I would really like to buy a small utility trailer,to haul my lawn tractor to in-laws for snow plowing etc.Problem is,no extra money for that stuff right now.The other question I just thought of is,do I need an 1 7/8" ball,or a 2" ball? or both?

 

ok good, glad you took care of the maintenace side of towing! for the ball, just ge tthe one for the size trailer you have. wehn you get the trailer, they will tell you what size ball it will take.

 

Huh? is this related?

 

Just rent a trailer from U-Haul for just $20-$30 per day depending on size.

As for hitch ball, there are 3 sizes: 1 7/8", 2" and 2 1/8". I find the 2" being the most commonly used and generally compatible with all.

 

Thanks Harrier,sounds good.

 

Okay, just stumbled on to this thread. I too am trying to do the trailer hitch thing on my '99 RX300. Yep, have the towing prep pkg. I'm just a little confused about the wiring harness. I've looked under the car and removed the black rectangular cover in the left rear. No evidence of a harness connector hanging about. Previous posts have mentioned the spare tire compartment. Nothing there either. Are you talking about the small cargo tray on the LH side, next to the spare compartment? If I remove the tray, should I find what I need lurking in there? If so, do I understand it correctly that I should be able to plug in the harness from etrailer? http://www.etrailer.com/p-118245.htm

 

SAMT,Mine was under the black cover under the vehicle.This black cover cover`s up the charcoal canister.loosen up the bolt`s that hold it in place (towards the rear of the vehicle) and it`s under their.It comes out of the wiring harness all by itself.I am surprised your 99 didn`t all ready have a hitch on it.? If you have any more questions,send me a private message.I`ll be glad to help you out.

I bot the hitch and cable extension from etrailer. The installation was really easy. The cable was just plug in after opening the black box under the trunk area. I have 2001 AWD, towing package prep.
