Rear End Grinding Noise While Accelrating

The rear end grinding noise issue.

At our auto repair garage we have deal with lots of vehicle with such such issues.

One more with same problem,this time it was 2005 Ford explorer.

The vehicle made grinding noise while accelerating only.Then the noise will not continue further.But these noise will always occur while start up.

So as per these types of problem already seen and noticed at our garage.

There are two possibilities,either its a issue with bearings getting worn out or the major issue is with transmission going out and needs a rebuilt by proper professional.


The 2005 ford explorers has a lot of rear end concerns, and it sounds like to me that it is a bearing going out in the rear end.
Inspect the bearing visually to confirm the problem.try cleaning the dirt collected on side of bearing first and view its actual condition,If it looks out of alignment and worn out,then it has to be replaced/.


But if the vehicle is making winding noise while going to drive mode and if the vehicle shakes a bit while start up,then it points out towards the faulty transmission.


So inspect the condition of your vehicle,as per what conditions are there,you can further go in that way,to resolve the problem.

These details will help.

DSG automatic transmission problem

VEHICLE: 2009 Volkswagen Golf
Transmission details: DSG automatic transmission
ENGINE: 1.4 TSI petrol.

PROBLEM: Vehicle Suddenly Took OFF While Parking

Why the car suddenly takes off while driving?

TROUBLESHOOTING SOLUTIONS:

First of all i will say that these types of issues are known.Many of our customers come with this types of problem at out repair garage.

Issues are very commonly known and noticed on  DSG gearboxes.

The problems noticed are like, when you go to pull away from stand still there is a delay and then a harsh jerkness forward, more so in slow speed conditions, there is always going to be a small delay from standstill to pull-away .These problems are noticed because of the DSG gear box design.

The DSG gearbox is designed to do this as it selects 2 gears at once, and initially you pull away in 2nd gear , then it drops down to 1st when it sees the wheels rotating.

Also the known problems with either the clutch packs or the Mechatronic control unit, which cause these similar problems that you have experienced.

I suggest you to get these issue checked/inspected by dealer. It is a main dealer issue.

Also when replacing these components as they have to be set up and a basic setting carried out .

The parts are not cheap to replace, the Mechatronic unit on its own is around £1400 just for the part.

There was no actual recall or service bulletin released by VW about these problem.But these same problem is noticed on many VW vehicles with DSG transmission gear box.So they must be very much aware of this issue and can get the correct part replaced.If you have no warranty left and if this is the faulty component, i would ask the main dealer if there is any "Good Will" from Volkswagen regarding this issue, and they may contribute towards the repair, sometimes they will pay for the whole repair.

These details will help.

Thanks.

2004 Toyota Sienna: No Reverse?

Gears enge in drive mode and vehicle runs fine.
The Shifting is good from neutral to drive and car starts/ runs good.

If all this is good,then first check the transmission fluid level.If its low then get the tranny fluid changed.
But if fluid level is good and shifting is good in all other modes except reverse mode then its transmission issue.

If the shift linkage and shift mechanism inside the vehicle is moving normally with no binding then a problem with reverse is in the transmission. There is no electrical solenoids or controls for reverse. It is strictly hydraulic over mechanics. You're going to have to have the transmission torn down to inspect the failure. The only other option would be to replace it with the used transmission.

This details will help.
