#3 of 14 Rear Suspension solutions
Dec 10, 2007 (8:49 am)
Recently Iought my uncle's 2004 Limited because I wanted to tow a small travel trailer (1800 lbs, gross.) I had installed the genuine Toyota Highland hitch and tail light converter. The Highlanded did a nice job handling my little trailer as I tower her from the California shore up the Colorado Rockies to Denver, where I left her for refurbishment. For the record, I got 15mpg towing at 65 mph. But with the trailer hooked up, the rear end of the Highlander sags a bit. Tongue weight is about 150 lbs, and I had some gear in the car, not much. Is there an aftermarket "suspension helper" than I can turn to? Air lift Company doesn't provide a product for the Highlander. Pep Boys sells a little aluminum block to wedge in the coils for some extra lift, but I don't like their solution. Anyone have any advice for an adjustable aftermarket suspension helper? Thanks. Michael

Michael...I have exactly the same vehicle and trailer sagging concern. I'll be interested to see what kind of response(s) you get. In the meantime I'm going to be checking with the local suspension shop people who installed my hitch and wiring (they did a nice job and were very knowledgeable) as well as the local Toyota service manager and suspension tech in the next couple of weeks to see what their recommendations are. I'll post here if/when I get an answer.

HERE IS FURTHER DISCUSSION on Equal-i-zer Hitch solution to rear end sag whilst towing a light trailer with the Highlander. I inquired whether the 250 lb tongue weight threshold (referenced in the earlier response) was critical for effective use of the Equal-i-zer Hitch. Here is the informed -- and almost immediate -- response:
So given this information -- and absent any good reason NOT to use a weight distribution hitch on my Highlander -- the Equal-i-zer Hitch solution for easing the excessive rear end sag seems to be in my future.

THIS POST SHOULD PRECEDE THE POST ABOVE IT, SINCE IT INTRODUCES THE CORRESPONDENCE FROM THE EQUAL-I-ZER MANUFACTURER. READ THIS FIRST TO MAKE ANY SENSE OF THIS THREAD. THANKS.

The Toyota Highlander is more of a car than a SUV and does not have a suspension system suitable for the use of Air Lift products. I am considering the Equalizer hitch. However, if you have any luck with your inquiries, please advise the forum; I'll track the thread. Meanwhile here is a copy of my correspondence with the Equal-i-zer people, who responded within a day to my inquiry. Right away I like their product.
“I have a small vintage 1955 Airstream-type aluminum airframe trailer, I think gross vehicle weight is 2000 lbs, could be higher after I finish modernizing the systems. My tow vehicle is a 2004 Toyota Highlander which is rated by Toyota (with tow package) at 3500 lbs. However, the coil over shock independent rear suspension disallows the installation of an Air Lift product. And I am suffering some rear end sag on the vehicle (which is really a car, not an SUV, irrespective of it's profile.) Would your lightest duty weight distribution hitch be a good solution for relieving the rear end sag on my Highlander whilst under tow? I appreciate that most Equal-i-zer hitches are used on bigger, heavier trailers. But is there a compelling reason why not to use one on a much smaller, lighter trailer such as mine?
The Equal-i-zer hitch would provide you with sway control and the weight distribution you are seeking. However, the Equal-i-zer hitch has a minimum tongue weight requirement of 250 lbs. As long as you loaded tongue weight is at or over this 250 lb limit, you should be fine to use our 6,000/600 lb rated Equal-i-zer hitch. There is no downside to using an Equal-i-zer hitch on a smaller trailer. All it can do is give you good weight distribution, and the sway control goes a long way in keeping you safe while towing.
Let me know if you have any more questions.

BECAUSE THE CONTENT OF THE POST ABOVE WAS REDACTED BY THE LIST MANAGER, I AM REPOSTING IT HERE. IT ANSWERS MY QUESTION ABOUT MINIMUM HITCH WEIGHT AND THE EFFICACY OF THE WEIGHT DISTRIBUTION HITCH BY EQUAL-I-ZER. (Whew...)

RE EQUAL-I-ZER weight distribution hitch.
The 250 lb tongue weight limit is a critical component in the way that the Equal-i-zer hitch provides sway control. The Equal-i-zer hitch uses steel on steel friction to provide sway control, and our engineers have stated (through testing) that you need to have at least 250 lbs of tongue weight in order to have enough friction occurring to provide you with sway control. If you have less than 250 lbs the hitch will still give you good weight distribution, but we cannot guarantee what kind of sway control you will receive from it. Let me know if you have any other questions. Thanks,

I contacted etrailer about their REESE light tongue weight WDH, called Product Number 66041 a 350 lb WDH which seems more appropriate to the small trailer. Installation instructions select for conditions where tongue weight is above 200 lbs or below 200 lbs. I believe my little 15' aluminum airframe vintage trailer will prove to be in that range. (I hope my experience learning about how to improve the trailer towing characteristics of our V6 Highlanders will be helpful to others.) Here is the almost immediate reply by the customer service rep to my email inquiry. I have been very impressed with customer service reps' willingness to provide a prompt reply to a question.
#11 of 14 Regarding struts
Aug 28, 2008 (9:24 pm)
I have a 2005 toyota highlander 6 cylinder and I am experiencing alot of body roll when making turns. Recommendation from my tire guy is that I replace my original equipment with after market equipment such as monroe sensamatic struts. He says they are better than the original equipment, will not leak as fast, and give me a better ride overall. My toyota service adviser disagrees and thinks that if I want to replace them I should stick with original equipment. He also says that he "has never had to replace struts on any highlanders under 90,000 miles. Does anybody have experience with this? What is the real recommendation? Thanks.

Back in October '06 I asked if anyone was making any modifications on the Highlander suspensions. Now I have 125k miles on the car and I'd like to replace the struts, as they are old and getting soft, and I'd like to lower the car at the same time. I've found some parts that will interchange from the Lexux RX300, but not enough to do the full job on a 4cyl, 2WD car. TRD-Japan does list the necessary parts but they cannot be obtained in the US and they would be an expensive option. Any ideas?
