1990 Miata with 1.6 with shimmy in possibly the driveshaft.

I have a '90 Miata with a 1.6, I have only had it for about a month, I have started driving it on a regular basis to work and noticed a shimmy feeling in the car, I took it and had the wheels balanced and rotated over the weekend, but as I was coming in to work today, I noticed the shimming is still there, to describe the shimming goes something like this, at about 60-70 mph, the car vibrates for a time then stops for a time, it's like the driveshaft is unbalanced, after the wheels were balanced, the vibration in the car has stopped but the shimming has continued... does anyone know what the shimming may be... thanks for the help...

i would think it is more likely due to a wheel bearing. the question is which of the four. i ended up replacing all of mine at about 110,000 miles because of a little shimmy in the front at high speed. the ones removed just fell apart and did not require a press to remove them so it was good to have done them all.

Miatas are very sensitive to wheel balance. You need a better balance job. Find a shop with a Hunter GSP9700 here:

I should mention that a bubble balance with a knowledgeable tech will do a MUCH better balance job than a spin balancer that is out of calibration. My personal experience is that a LOT of spin balancers are out of calibration, probably most of them.

The OP might take the tires back to the original shop, ask them to rebalance the tires after calibrating the balancer. It's not hard to do but most shop will never do it.

Make sure that all 4 tires are inflated between 26 psi and 28 psi.

I appreciate all the advise, I'll check the wheel bearings when I get home....I really like this site, there are alot of knowledgable folks out there when it comes to dealing with the little Miata... Thanks again.... Trent

I'm little. That makes my Miata BIGGGG. LOL

Yes, as much as I wouldn't mind a few extra inches in height and a little extra weight, the miata looks like it was designed for someone my size. If it had a tilt steering wheel, it would never be used by me.

Have you ever seen a really big person in a miata? It looks funny as hell. I have a friend who is 6'5" with long legs/short torso. His head fits underneath the top, but his knees were up around his ears. He went on exactly one ride and said no way, ever. I agreed with him. I don't think it would have been safe for him to drive it.

I know that there are a lot of very tall and/or heavy people driving miatas that make do, but that is exactly what they are doing, making do. There is no way that the car fits them as perfectly as it does to someone close to my size.

I'm 6'4" with a 34" inseam and the Miata fits me perfectly, as if designed specifically for my size. I've driven it on trips of around

400 miles or so and am completely happy with the fit.

It's also white, maybe white Miatas fit better as well as being faster? Leon can explain it, I'm sure.

Yes, I am sure that Mazda looked at the potential miata market and said, "let's design the car to fit people who are 6'4", since that is the average height of people around the world, especially in America & Japan". ;-)

You have me by 7 inches in height, but only 2 inches on the inseam. That means your head is very close to the top when the top is raised. If you were built like my friend, who probably has closer to a 38" - 40" inseam, (I don't ask guys stuff like that), it would not fit you well at all.

BTW, 400 miles is nothing, I have done that many times to the Mexican border and back. 3600 miles in 12 days is a little more taxing, but it was still comfortable to drive. I don't think Leon would have been too comfortable on his Florida to Alaska and back trip if he was double his size, no matter what color miata he was driving. :-) I am talking about width as well as height, and leg length means a lot with this car.

I can wear an Australian Bush hat with the top up, there's enough clearance. Your Miata must be MUCH smaller than mine.

Correct. 6'3" or less = midget, 6'5" or more = giant, 6'4" = perfect!

Actually the Miata was designed entirely in California and it was designed to fit large people.

Having said all that, the original design has apparently been lost, I don't fit in the current model at all as has been previously been discussed. Sooner or later I'll sell the 1992 and then I'll probably be out of the Miata world.

It's not only fit, the chances of me buying a car w/o a spare tire are less than the chances of the Arizona Cardinals winning the Super Bowl. Of course, it's been almost 3 weeks since I had to use the spare...

The thought of you driving your miata around while wearing an Australian bush hat is just too damned scary, but I still want to see. Do you have a picture of this frightening scenario?

At least it is my miata that you called smaller.... ;-)

Large is a relative term. My friend fit his Ford Bronco very well. As I said before, he was probably incapable of driving the miata safely.

It also is not so much height as width. On average, we are getting fatter and fatter, there is a certain limit to how wide an ass that seat will hold. There is also only so much room between the door and the console even if the person flabs out over the bolsters. It is very much a double-seat on the airplane situation without any options.

But hopefully you will stay here. We love you, XS11E!

Who in the hell are the Arizona Cardinals? Is that a sports team? ;-)

Nope. I wear it for camouflage, I work at the Phoenix Zoo and with my uniform shirt, khaki trousers and the hat I blend in perfectly with everyone else.

BTW, Phoenix summers demonstrate the effectiveness of the hat as a sun shade, it works better than most anything else.

When I read that I thought, man that is a dangerous zoo where the keepers have to hide from the animals. ;-)

Cool, do you have sulcatas there? (African Spurred Toroise)

No, sorry, we have no African Spurred Toroise. We do have some African Spurred Tortoises but I'm not sure if they're currently on display?

Some months ago I was giving a tour of the zoo and we stopped the cart to look at the baboons. Across from them is the Mohr's Gazelle enclosure and at that time there were at least two of the spurred tortoises there hard at work making more spurred tortoises. One of the other volunteers came by, looked at the scene and commented to me, "We're going to get letters!"

We always do when sex happens, damn critters insist on behaving like... well, like animals!
