4runner newbie with some maintence questions

hey all, I recently became the proud owner of an '04 4Runner Limited. Got the car with 55,700 miles, In the two weeks I've had it, I've put nearly 1k miles on it (road trip this weekend).

I'm loving the vehicle so far, however I am taking it in to the shop on Tuesday for the following issues:

1.) Sulfur smell when accelerating (mainly noticed with tailgate window down) - I saw the TSB on this and figured I would get it done since my car is still in warranty.

*note on issues 2 and 3: These issues are still present after having tire alignment, rotation and balance done last week at my local Firestone.

2.) Steering wheel pulls slightly to the left at times. The Runner came with Dunlop AT20s on it. The tread looks to be in pretty good condition, I don't know if they are the original tires that came with the vehicle or not.

3.) There is a very noticeable steering wheel vibration (shimmy?) that occurs between 60 and 75mph (don't really go much faster then that, so not sure if it happens above that speed) When this occurs, the steering wheel will shake harshly. Whats extremely weird about it is that it is not consistent, sometimes it will shimmy at 65mph, other times it will be smooth. Sometimes it will start out shaking at 70mph and then smooth out, only to start again when I go back down to somewhere in the 60s.

4.) The engine seems to have a high-pitched wine when in park or neutral. It goes away if I put the vehicle in drive or reverse. This noise may be within standard specs, what do you guys think?

5.) Service TSBs - ok, I'm aware that there are multiple TSBs out there for my vehicle which i seem to still be eligible for under warranty. I am not familiar with the process for these. Should I go into my Toyota dealership (note: i bought the car from a dealer several states away, this is just my neighborhood toyota dealership where I will be getting future work done) and insist they perform all TSBs? Would they even do that?

This 4runner is the first car I've purchased on my own (I'm only 24, all my previous cars have been handme downs from my parents) so forgive me if Im asking simple questions, I'm really hoping people here can give me some tips on how to proceed with the issues above.

thanks!

Congrats on a great ride.

Your ride issue is probably due to tires that have worn irregularly. Even though you did an alignment and balance, you may just have tires that are "gone."

If possible, I would go to a 'high end" shop, have them again balance with a road-force machine (Hunter 9700 etc), check for bent wheels and be sure that mechanically your ride is go to go. If this fails to fix or illuminate the problem, then new tires are in order.

Good Luck and let us all know how this all plays out.
 
hi Allegro, Thanks for your reply!

So you think issues 2 and 3 are both caused by shoddy tires? I don't know much about tires, but some quick research on the Dunlop AT20 (google) seems to suggest that they aren't the best tires out there. If I were to move forward with new tire purchase, any suggestions on what I should look at?

could you give me an example of a "high end" shop? How would I go about finding one? I'm assuming the Firestone I usually go to for regular maintenance doesn't qualify?

Thanks!
Eric

Welcome and congrats!

So many tire choices... Firestone shops as a rule don't qualify as good shops but there are some specific shops that are very good. If you have one of those look at a set a set of Revo 2's. 265/70/17 will fit with no rubbing, no issues and are often times cheaper. You DON'T want the LT265/70's, you want the regular P265's.

On question 4, does the whine go away or change if you move the steering wheel while in N?

The dealer will only perform the TSB if your 4Runner exhibits the issue. They won't do the work just because your 4Runner is listed on the TSB and the issue is not happening.
