      [IMPORTANT] Club smart Car Website Migration - July 2024   07/07/2024

      Hello everyone, we will be looking to migrate the Club smart Car website to a new web host and update the software so that it is on the latest version and has security features such as HTTPS:// which is now the industry standard. A lot of web browsers are marking the website as Not Secure due to this.   In the coming days, you may notice this website go offline in its current form. You will be redirected to a new website URL which will be in use to direct you to the new version of the website. We are hoping to obtain the ownership of clubsmartcar.ca and clubsmartcar.com so you can continue using these links in the near future.   The new forum will look slightly different aesthetically, but will contain all the forum posts from the many years this community has existed! This was the most important to the group looking to keep the community going. Your usernames and passwords will also remain the same.   Unfortunately, the Wiki portions (including the VIN database) will not be able to be migrated in its current form, but the list is preserved and we will look to have the information available again in time. The chatbox will also be removed.   This step is important for the continuity of this community. We are very grateful to those who have graciously run the website in the past, however, currently we have no guarantees of the website continuing on, so we are taking these steps while we can, to keep Club smart Car going into the future.   If you have any questions, please comment in this thread. Otherwise, please stay tuned for the new website URL!   Thank you, -Awesys

Steering feels quite stiff!

17 posts in this topic

Hi all, new to this forum as I just bought a smart car this week so hopefully you guys can help me out!

 

The smart car is running fine, however, the steering feels slightly stiff, I don’t know whether to put it down to the fact that temperatures have been extremely cold here as of recent, however, I have looked on other forums and it has advised me to grease the rubber flange in the footwell of the drivers side as this is all it may need, however it didn’t say any other steps...

 

so was was just wondering if anyone had any advice on this? 

 

Thanks guys.

Welcome.  Have you compared the steering feel in your car to others, has it changed in the few days you have owned the car?  What is the year and mileage of your car?  Is your car equipped with power steering?  Is the inflation pressure correct in the front tires?

Lower universal joint (15x39) is prone to seizure as  exposed to the elements where it sits behind radiator. 

Easy to replace if you have the necessary skill and wit. 

Also easy to screw up and ruin steering wheel clock spring. 

 

My lower universal joint startet getting stiff  recently.  I opened out and greased lower UJ a couple of years ago. The seals were worn so water must have gotten inside. Will now bite the bullet and renew lower UJ. Bought one on EBay for £7. Febest AST-1539. 

PS. Unwise to grease rubber boot where steering column penetrates.

 

PS2:  A15x39 UJ fits a 450. Not sure what UJ a 451 has.

Lubing won’t last long.

Oil or grease won’t make the rusty pins turn.

My steering is very stiff when starting up a cold car, but it gradually becomes more "normal" after the car is driven for a bit.  Is that what others are finding, or does your steering stay stiff even after the car is fully warmed up?

I don’t find mine stiff at anytime.

2013 40k miles, stiff after 4 days of non use.

Get easy sometimes then harder.

Seems like the needle bearings are ready to die.

Heading to dealer in the AM.

To prolong life of your lower universal joint I suggest fully wetting its seals in grease or chain bar oil. The grease will keep seals wetted slowing down ingress of dirt and water into the bearing cups.

 

Once the UJ starts getting stiff, one or more of its seals are worn allowing water free access.

Photo shows my lower UJ being removed.  All needles were seized in the cup.  No sign of grease, only dirt and rust.  Of course there is not much grease there to start with.  A real pity we cannot source UJs in this size (39x15mm) with grease nipple fitted.

was this from a 451? I'm looking at photos of the steering columns at the wreckers and the joints seem steaked so no way to remove/replace it with the febest u-joint

You can restake the u joint cups or make special clamps to hold cups in place like shown in below YouTube video:
