The players came up against each other in an FA Cup fourth-round tie at Loftus Road in January, when in a bid to dilute the tension the Football Association gave permission for the teams not to partake in the handshake, amid uncertainty as to whether Rangers defender Ferdinand would snub Terry.
But the Premier League insist there are no plans to drop the handshake at Sunday's game, and have not had a request from either QPR or Chelsea to do so. Terry was accused of racially abusing Ferdinand during the league match in October, a complaint was made against the Chelsea defender and he was charged with a racially-aggravated public order offence by the Crown Prosecution Service in February. He will stand trial on July 9 and vehemently denies the charge.
Rangers go into the game on the back of four straight home wins - a sequence that has dragged them three points clear of the Barclays Premier League relegation zone, but their away record is the worst outside the bottom three.
Ferdinand, who impressed in Saturday's win over Tottenham, knows his team are not safe yet but hopes they can move further clear of danger by pulling off their first win at their local rivals since 1986.
"The Tottenham win was a massive win that could push us on to safety - but we're not safe yet," Ferdinand told www.qpr.co.uk.
"We can't for one second think that we're safe. We've got to make sure that we continue push on.
"Now it's time to try and get something away from home next weekend (at Chelsea), and carry on the form that we're showing at home."
Many thought QPR were doomed after being handed the toughest run-in of the teams avoiding the drop, but they have registered home wins over Arsenal, Spurs, Liverpool and Swansea to climb out of the bottom three.
As well as Chelsea, Rangers also have to face title-chasers Manchester City in their last four games, but Ferdinand is not scared of taking on the top flight's biggest teams after their recent accomplishments.
"We showed great team spirit on Saturday and we've shown that we can play against the top teams," he added.
"We've shown that when needs be, we can stick together and win important games.
"It was a fantastic performance all around. We know that when we're at home, we're hard to play against.
"The team were hard to beat, and we were also very good going the other way. It was great to see."
QPR chairman Tony Fernandes has pumped millions in to the west London club since he took over last summer.
He must have been worried his investment would go up in smoke after the club's terrible form in the middle of the season, but he is now happy that his team are on the up under Mark Hughes.
"There's still a long way to go, but those that wrote us off three or four weeks ago might be thinking again now," Fernandes said.
"It's a big advantage to have points on the board at this stage.
"We can't count our chickens though, because we've still got some very tough games ahead, but I believe in this team.
"We've got a great manager and a team of players who are producing the goods now, especially at home.
"We just need to keep our fingers crossed and get over the line and build for next season."
