I have to say that after spraying the u-joints with 3-in-1, the steering is much better. I drove 400 miles last weekend and wasn't constantly fighting the wheel. Still, not as good as the old hydraulic power steering assist or other EPS cars I've driven, but better and livable. I can't imagine that oiling the u-joints making such a change since they are fairly straight to start with. very little steering wheel movement makes less u-joint movement when the input and outputs are very close to in-line. I wonder if overspray or run-down getting into other bearings or seal at the footboard is the real fix? Whatever the root cause, it did help, a lot. Thanks.
I used the 3 in 1 oil with the extendable spout (extends to 15 cms) and oiled both sets of U-joints. This made the job easier. Although one needs to be a contortionist to get at the upper joints without removing any components to access.
To early to report if steering performance is better but I am hopefully optimistic as it does seem to be a reasonable idea in fixing this issue.
this fix is to free steering columns from at rest sticking. Drift, ZigZag, etc..
this fix will not correct improper alignments
this fix will not correct uneven air pressures in tires
this fix will not correct uneven tread or unequal tires on vehicle
this fix will not correct bent rims, bad ball joints, broken shocks, bent control arms or bushings..
how many miles you have xavis?
ever change out your tie-rod ends?
Tie-rod end joints dried up, lower ball joint dried up?
(providing needle bearings properly oiled)
These things listed above are all of concern..
and ball joints do dry up.. especially if a boot is cut
should be as close to Zero as possible with a touch of positive toe
I'm saying a Touch.. like .02 would be nice as a total toe..
and yet another possibility that may also apply to the people..
it is such a Bad grease used in production, that it is possible for needle bearings to wear down to having flat spots over time..
especially true if your intermediate shaft installation was done on a Friday or Monday
(lazy days of production)
pressure tires 32psi ok
15000km or 9600mill
the car only 12 months
all as greasing your drawings u joint with 3 in 1 several times over several days.. but only happens to me when I drive in a straight line with the steering wheel in the center, it is difficult to find the right center , and is a bit sticky. although it seems a little less than before
.I think it's something that hardens a little electric steering wheel when this right but are not .
UPDATE: I brought my 2015 Elantra in for service last week and mentioned the issue of rough steering feel and hard to keep the vehicle in a straight line on the highway. Since my vehicle is under warranty they took it upon themselves to replace the intermediate steering column. The cost would have been $1,200 as per the work order I saw at the time but did not receive. I just drove it home as my wife is the primary driver but it seemed smoother than before. I'll ask my wife what she thinks. I was going to mention the lubing of the U-joints in the column. I assume this is a common issue if they had the part in stock already?
The next issue is the rear toe still being off but within spec EVEN after the dealer performed a 4 wheel alignment. I plan to get a second opinion on the alignment printout I have and explore the shims to correct the rear toe.
Something weird happened to my 2015 Elantra. My daughter opened sits behind me on the driver side. She opened her window with the button on her door. When we asked her to close it, she said she couldn't. She was pulling in the button to close, but it wouldn't. I was able to close it on the...
Car has about 96,000 miles on it. If it's got a tranny problem I want to get it fixed before I hit the end of the warranty. Engine was already replaced at 88K miles under warranty by the previous owner, I got it at 95,000 miles. I've put an oil change and brake pads + rotors all the way...
Hey guys, first time poster. I keep getting code P0106 on my 2013 Hyundai Elantra. Upon further research that is for the MAP Sensor. I got this code today after startup, and 3 weeks ago while I was driving. I had an ECM code then too but do not now. The car then would not let me go above 50MPH...
